I will discuss why the discovery of an axion-like particle above the QCD line would rule out Grand Unified Theories\, both in 4 dimensions and in higher-dimensions\, and the perturbative Heterotic String.

SUMMARY:Luigi Bellafronte - 'Exploring Precision Physics at Future Colliders'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/462
DESCRIPTION:In recent years\, the Large Hadron Collider (LHC) at CERN has increasingly focused its attention on the precise measurements of Standard Model (SM) processes\, as they play a crucial role in the exploration of new physics. The emphasis on precision physics has also motivated the development of the high luminosity (HL) LHC upgrade and the proposal of new high precision machines such as the FCC-ee.  In this context\, the theoretical effort has to match the experimental work\, because precise measurements require an equal precision of the SM predictions. The aim of this seminar is to discuss the precision calculation of processes in the SM and Standard Model Effective Field Theory (SMEFT) framework\, including electroweak observables\, Top-Quark–Electron interactions and single Higgs production. The study of this area is very important and it gives crucial information on the structure of new physics beyond the SM.

SUMMARY:Pablo Navarrete - 'The thermodynamics of hot and dense QCD from perturbation theory'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/461
DESCRIPTION:The weak-coupling determination of the QCD pressure has a long history\, driving advances in effective field theory and multi-loop techniques that have reshaped thermal field theory. At high temperature\, it provides a clean benchmark for lattice simulations\; at high baryon density\, where lattice methods are hindered by the sign problem\, it offers the only first-principles constraint on the equation of state of neutron-star matter in this regime. In this talk\, I will review the development of these calculations and their present status in both limits\, where the frontier now lies at O(g^6) in the gauge coupling\, or four loops. I will also briefly outline a novel idea that makes an O(g^9) computation at high temperature and density not only possible in principle\, but feasible in practice.

SUMMARY:Tisa Biswas - 'Gauge Choices\, Infrared Pitfalls\, and Thermal Effects in Effective Potentials'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/460
DESCRIPTION:The evaluation of effective potentials is critical for a range of phenomenological applications\, including inflation\, vacuum stability\, and phase transitions. Their use in gauge theories\, however\, is complicated by gauge-parameter dependence and\, in theories with spontaneous symmetry breaking\, by infrared singularities associated with massless Goldstone modes.In this talk\, I will revisit these issues in the Fermi gauge at one-loop order. I will show that the non-factorisation of regularised elliptic operators gives rise to a multiplicative anomaly\, whose inclusion simultaneously removes the relevant gauge-parameter-dependent contribution and restores the corresponding Landau-gauge infrared behaviour. I will then discuss the Heat Kernel formulation\, which treats the matrix elliptic operator directly and makes the anomaly-related cancellation transparent from the outset. Finally\, I will describe how this framework extends to finite temperature and briefly comment on subsequent developments in thermal effective field theory and cosmological phase transitions.

SUMMARY:Oliver Gould - 'Gravitational waves from critical dynamics'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/459
DESCRIPTION:The critical\, universal behaviour of any second-order phase transition gives rise to stochastic anisotropic stresses. These in turn source a stochastic spectrum of gravitational waves. In this talk\, I show how to derive the rate of gravitational wave production for second-order phase transitions in the simplest dynamical universality class\, Model A\, describing a diffusive scalar order parameter. The result is a broken power law which grows towards high frequencies.

SUMMARY:Lorenzo Mai - 'What do Jet Substructure and Electroweak Interactions have in common?'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/457
DESCRIPTION:At first sight\, jet substructure and high energy electroweak interactions appear as complementary areas of collider phenomenology. In this talk\, I will explain why they are nevertheless connected through a common theme: the emergence of large logarithmic corrections that require dedicated theoretical tools for precise predictions.I will begin with a brief personal introduction and an overview on jet substructure\, presenting a selection of infrared and collinear safe observables of interest on both an experimental and theoretical perspective. I will highlight how theoretical predictions for such observables are plagued by large logarithms which spoil the reliability of perturbation theory and hence need to undergo a resummation procedure.I will then turn to my second research line\, focusing on electroweak corrections in the high energy regime\, where they are logarithmically enhanced by the large hierarchy between the characteristic scattering energy and the electroweak gauge-boson masses. At next-to-leading order (NLO)\, these Sudakov logarithms can give rise to corrections of several tens of percent in the tails of kinematic distributions for key LHC processes\, while they still contribute at the few-percent level at next-to-next-to-leading order (NNLO). Their inclusion is therefore essential for achieving the level of theoretical precision required by current and future collider measurements and for reducing uncertainties associated with missing higher-order corrections.

URL:https://ftae.ugr.es/index.php/pages/event/seminar/455
DESCRIPTION:Dark matter constitutes most of the matter content of the Universe\, yet its particle nature remains unknown. Charged cosmic rays provide a powerful avenue to search for possible dark matter signatures through anomalous contributions to the observed fluxes of antimatter. In this talk\, I will discuss the status of indirect dark matter searches across multiple cosmic-ray channels. After reviewing the main theoretical framework and relevant astrophysical backgrounds\, I will present current observational constraints from cosmic-ray measurements and discuss the main associated uncertainties. Finally\, I will highlight the potential of cosmic rays to probe dark matter models beyond standard WIMP scenarios.

SUMMARY:Matteo Saccardi - 'Smearing QCD spectral functions from first principles'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/454
DESCRIPTION:Spectral densities encode key QCD observables\, including inclusive hadronic decay rates\, cross sections\, and transport properties of the quark-gluon plasma\, to name a few. Their Laplace transform corresponds to Euclidean correlation functions\, which can be accessed non-perturbatively from first-principles lattice QCD. For realistic scenarios\, where only noisy and finite discrete samples of the correlator are available\, their extraction amounts to an ill-posed inverse problem. In this talk\, after reviewing a few phenomenologically relevant instances where the non-perturbative extraction of smeared spectral densities is timely\, I will revisit selected strategies for reliably tackling the inverse problem. Once the field-theoretic properties of causality\, analyticity and positivity are encoded in the solution\, tight bounds on smeared spectral functions become accessible via a lattice bootstrap program.

SUMMARY:Eung Jin Chun - 'Spontaneous Leptogenesis in Type I Seesaw'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/453
DESCRIPTION:Type-I seesaw models with a spontaneously broken  B-L symmetry provide a natural framework for spontaneous leptogenesis driven by a Majoron. In this framework\, the Majoron's kinetic background acts as a CP-violating source\,  generating a lepton asymmetry through both tree-level decays and equilibration processes via inverse decays of right-handed neutrinos.  We construct and analyze  the Boltzmann equations incorporating both effects simultaneously for the first time.  We then apply this formalism to QCD axion models integrated withthe seesaw mechanism to demonstrate how this approach enables the cogenesis of baryon asymmetry and dark matter.

SUMMARY:Sourav Bera - 'Differential observables for the Higgs-strahlung process to all orders in EFT'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/451
DESCRIPTION:We develop methods to obtain the fully differential cross-section for the f f \\to Z(ll) h process to any desired order in  effective field theory (EFT). To achieve this\, we first derive a mapping between the partial wave expansion and the EFT expansion to all orders. We find that at lower orders\,  EFT predicts correlations between the different partial wave coefficients. This allows us to construct linear combinations of partial wave coefficients that get their leading contributions from a higher dimension EFT operator. We then introduce experimental observables\, the so called angular moments -- that probe these linear combinations of partial wave coefficients --- and can be determined from a fully differential analysis of the angular distribution of the leptons arising from the Z-decay. We show that analysing the dependence of these angular moments on the Zh invariant mass allows us to systematically probe all higher dimension EFT operators contributing to this process. In particular\, we discuss how our results can be used to probe dimension-8 operators in the Standard Model EFT (SMEFT). While we take the Higgs-strahlung process as an example\, the methods developed here are completely general and can also be applied to other 2-to-2 collider processes.

DESCRIPTION:Neutrino experiments are entering the precision era\, opening new opportunities to test the standard three-neutrino paradigm and to search for signals of physics beyond the Standard Model. In this talk\, I will discuss selected examples of non-standard interactions (NSI)\, with emphasis on charged-current effects in neutrino production and on their description within effective field theory (EFT). In particular\, I will show how charged-current NSI in pion decay can help alleviate the tension between T2K and NOvA data\, and how similar effects may be probed at future facilities such as DUNE. I will also comment on how EFT provides a systematic framework to connect low-energy observables at neutrino facilities with ultraviolet-complete models\, and on the constraints this imposes on viable new-physics scenarios.

SUMMARY:Silvia Pla Garcia - 'The Schwinger effect: vacuum instability\, mode mixing\, and quantum signatures'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/449
DESCRIPTION:The Schwinger effect—spontaneous pair creation in a strong electric field—is a paradigmatic example of vacuum instability in quantum field theory. In this talk\, I will first give an overview of the phenomenon and briefly compare the most standard derivations. I will then explain why the Bogoliubov viewpoint is especially useful when one wants\, not only a production rate\, but also a description of the quantum state of the produced excitations. This opens the door to quantum-information questions: when are particle–antiparticle modes actually entangled\, how does entanglement degrade\, and whether entanglement is expected to survive under realistic conditions in analogue platforms. Finally\, I comment on how the same mode-mixing logic can be related to the generation of entangled pairs in gravitational settings (including the Hawking process)\, and what are differences between bosons and fermions.

SUMMARY:Federico Buccioni - 'Violation (and restoration) of universality in perturbative QCD at high-loop orders: an amplitude-level investigation'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/448
DESCRIPTION:Factorisation and universality are key principles underlying precision predictions for hadron-collider observables. They enable the separation of short- and long-distance dynamics and allow different scattering processes to be related through universal building blocks. In this talk\, I will discuss how these principles are realised in perturbative QCD and how\, at high perturbative orders\, they can appear to break down. Focusing on the collinear limit of multi-loop scattering amplitudes\, I will describe the origin of factorisation(universality)-violating contributions and their connection to long-range colour correlations and Glauber modes. Despite these violations at the amplitude level\, universality is ultimately restored in physical observables through non-trivial cancellations. These results shed new light on the infrared structure of QCD and strengthen the theoretical foundations of precision collider phenomenology.

SUMMARY:Mikael Chala - '¿El universo primitivo experimentó transiciones de fase?'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/447
DESCRIPTION:Es bien conocido que\, partiendo de temperaturas de trillones de grados poco después del Big Bang\, el universo se fue enfriando hasta alcanzar unos mil grados un millón de años más tarde\, y unos -270 grados en la actualidad. Se cree firmemente que\, durante este periodo\, el universo pudo experimentar diversas transiciones de fase\, análogas al paso del vapor de agua a estado líquido a presión constante. El (casi) único rastro observable de este fenómeno a día de hoy serían ondas gravitacionales generadas por la colisión de burbujas de energía producidas en los cambios de fase\, detectables mediante experimentos capaces de medir vibraciones inferiores al tamaño de un protón en detectores de varios kilómetros de longitud. Ejemplos de ello son LIGO y Virgo\, o el futuro detector espacial LISA\, cuya extensión alcanzará millones de kilómetros.Sin embargo\, el estado actual del desarrollo teórico no permite establecer con certeza si eventuales señales registradas en observatorios de ondas gravitacionales tendrían un origen genuinamente cosmológico o si\, por el contrario\, podrían atribuirse a fenómenos astrofísicos más “convencionales”\, como la fusión de agujeros negros. En esta charla abordaré los principales retos que implica mejorar\, en varios órdenes de magnitud\, la descripción de la dinámica de transiciones de fase cosmológicas y de las subsiguientes ondas gravitacionales\; así como los avances logrados en esta dirección por el grupo de Física Teórica de Altas Energías (FTAE)\, mediante la aplicación de métodos desarrollados originalmente en el contexto de la física de partículas.Más información: https://ic1.es/index.php/el-universo-primitivo-experimento-transiciones-de-fase/

SUMMARY:Andreas Trautner - 'Goofy Symmetries'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/446
DESCRIPTION:I will pedagogically introduce the recently discovered goofy transformations. Originally\, goofy transformations were identified in explicit discussions of the two-Higgs-doublet model (2HDM)\, but their understanding is mandatory to describe the renormalization group (RG) fixed point structure of quantum field theories in general. Even though goofy transformations are\, by definition\, explicitly broken by the kinetic terms\, the parameter relations they impose on the potential can be stable under RG running to all orders. In the SM\, goofy transformations of the Higgs generally prohibit its bare mass parameter and are intertwined with the Yukawa couplings\, for what reason they may have important applications for the electroweak hierarchy problem and the Standard Model flavor puzzle.

SUMMARY:Journal Club Event: Andrea Sanfilippo - Tracing out massive fields in cosmology
DESCRIPTION:Cosmological correlators are calculated through the in-in formalism in (quasi-)de Sitter\nbackground. Its effective description is best represented by a reduced density matrix. In this work\,\nwe study how integrating out a massive field in de Sitter space determines the reduced density matrix\nof a light field at a finite observation time. Starting from a quasi-single-field model with non-linear\ncouplings\, we first evaluate the massive field wavefunctional at fixed final value and then trace over\nthis value. The trace generates branch-mixing terms which are generally present in the Schwinger–\nKeldysh description. For a conformally coupled massive field\, we show explicitly that the light\nfield bispectrum from the effective description agrees with a full theory calculation. This example\nalso shows that decay of a field at the future boundary does not by itself justify discarding its\ncontribution to the trace. We discuss the differences between an exact nonlocal effective description\nand the local effective field theory obtained through a large mass expansion. We then identify which\nlocal cubic terms affect the late-time probability and which contribute only a wavefunctional phase.\nFinally\, we organize the resulting kernels by response\, noise\, and Schwinger–Keldysh consistency\nconditions\, and discuss the symmetry constraints on the reduced density matrix.\n\nRef: https://arxiv.org/pdf/2609.30370

SUMMARY:Journal Club Event: José Miguel Martín Pérez - Spectroscopic Supermassive Dark Star candidates
DESCRIPTION:Dark Stars\, i.e. early stars composed almost entirely of hydrogen and helium but powered by Dark Matter\, could form in zero metallicity clouds located close to the center of high redshift Dark Matter halos. In 2023 three of us identified (in a PNAS work) the first three photometric Dark Star candidates: JADES-GS-z11-0\, JADES-GS-z12-0\, and JADES-GS-z13-0. We report here our results of a followup analysis based on available NIRSpec JWST data. We find that JADES-GS-z11-0 and JADES-GS-z-13-0 are spectroscopically consistent with a Dark Star interpretation. Moreover\, we find two additional spectroscopic Dark Star candidates: JADES-GS-z14-0 and JADES-GS-z-14-1\, with the former being the most distant luminous object ever observed. We furthermore identify a feature in its spectrum indicative of the smoking gun signature of Dark Stars: the He IIλ1640 absorption line. In view ALMA's recent identification of a probable OIII nebular emission line in the spectrum of JADES-GS-z14-0\, the simple interpretation of this object as an isolated Dark Star is unlikely. If both spectral features survive follow-up observations it would imply a Dark Star embedded in a metal rich environment\, requiring theoretical refinements of the formation of evolution of Dark Stars\, which in previous studies were assumed to form in isolation\, without any companions.\n\nRef: https://arxiv.org/abs/2505.06101

SUMMARY:Journal Club Event: Diogo Costa - Gluon production in the Color Glass Condensate from BCFW recursion
DESCRIPTION:In the Color Glass Condensate framework\, the colliding projectiles are described as classical color currents. Gluon production at leading order in the coupling is obtained from the retarded solution of the classical Yang-Mills equations\, with these currents acting as sources. However\, while the final gluon spectrum is gauge invariant\, the classical color field A^μ from which it is obtained is gauge dependent. This makes the intermediate steps of this approach unnecessarily complicated\, as some effort is spent to also determine the gauge dependent part of A^μ\, which is then discarded when one calculates a gauge invariant observable.\nIn this work\, we use a generalization of BCFW recursion applicable to off-shell gluons in order to calculate directly the gauge independent gluon production amplitude. This approach allows all manipulations to be performed in terms of gauge invariant amplitudes instead of gauge dependent Feynman diagrams\, and therefore provides a gauge agnostic way to obtain the result.\n\nRef: https://arxiv.org/abs/2605.02299

SUMMARY:Journal Club Event: Andrii Dashko - Probing the Kinematic Dipole with LISA: an analytical treatment
DESCRIPTION:The motion of the Solar System with respect to the cosmic rest frame induces a kinematic dipole\nin the stochastic gravitational-wave background (GWB). Detecting this signal with space-based\ninterferometers would provide an independent measurement of our peculiar velocity and a GW\nprobe of cosmic anisotropies. We present a fully analytic derivation of the response of the Laser\nInterferometer Space Antenna (LISA) to a kinematic dipole\, and construct an optimal estimator\nfor its detection. We show that the dipolar response is governed by a single frequency-dependent\nfunction fixed by symmetry\, and we compute its behaviour across the LISA band. Using Fisher\nforecasts\, we find that for a scale-invariant background detectability requires h^2ΩGW ≳ 5 × 10−8\nfor fiducial LISA\, and h^2ΩGW ≳ 5 × 10−10 for a detector with characteristic instrumental-noise\namplitudes improved by an order of magnitude. Prospects are more favorable for signals with richer\nfrequency profile. We also explore the potential of the kinematic dipole to break degeneracies\,\nparticularly in the presence of strong galactic foregrounds or noise features that closely mimic the\nprimordial signal.\n\nRef: https://arxiv.org/pdf/2604.08968

SUMMARY:Journal Club Event: Chiara Giuliano - When Two Loops Matter: Electroweak Precision in the SMEFT
DESCRIPTION:We identify a novel next-to-leading order renormalization effect in the dimension-six SMEFT with direct phenomenological impact. The Higgs-Yukawa operator that modifies the top-Higgs coupling κt induces a shift in the W mass at two-loop order through a large anomalous dimension\, rendering electroweak precision observables a powerful indirect probe of κt. We show that this effect is essential for the consistent interpretation of data from future Tera-Z and Giga-W factories such as FCC-ee. The effect is realized in a simple renormalizable two-Higgs doublet model.\n\nRef: https://arxiv.org/abs/2604.26817

SUMMARY:Journal Club Event: Maria Cristina Fiore - Quirks Live in Cool Universes
DESCRIPTION:We demonstrate that cosmological observations place strong bounds on the reheat temperature TRH of the Standard Model (SM) in minimal models of ‘quirks’ – heavy fermions transforming under the SM gauge group together with a new non-Abelian gauge interaction with a confinement scale far below the mass of the fermions. These models have unique collider signals associated with the confining flux strings\, which cannot break due to the large mass of the quirks. Our work shows that in these models T_RH <= O(100) GeV for the entire ‘quirky’ parameter space where the effects of the flux string are important. These bounds are in tension with most models of baryogenesis\, showing that the discovery of quirks at colliders can have far-reaching implications for cosmology. The bounds arise because the irreducible relic abundance of glueballs from UV freeze-in\, combined with their long lifetimes\, leads to constraints from the disruption of BBN\, distortions of the CMB\, excess γ-rays\, an over-abundance of selfinteracting dark matter\, and contributions to ∆Neff. The glueball freeze-in abundance has a strong dependence on TRH\, making the bounds relatively insensitive to strong interaction uncertainties. The bounds are robust to the SM quantum numbers of the quirks and the presence of Yukawa couplings with the Higgs. In non-minimal extensions\nof the model where the glueballs can decay to an additional dark sector\, the bounds remain for models where the flux string has a macroscopic length at colliders. We also show that for quirk masses above ~ 10 TeV\, the dark glueballs can be the dominant component of dark matter. This work illustrates a striking connection between quirky collider signals and cosmological probes of new physics\, strengthening the case for targeted quirk searches at colliders.\n\nRef: https://arxiv.org/pdf/2512.20696

SUMMARY:Journal Club Event: Fuensanta Vilches Bravo - Searching for axions with quantum interferometry
DESCRIPTION:Quantum phase measurements offer a complementary route to axion searches. We show that axion-photon interactions can imprint both Aharonov-Bohm (AB) and Berry phases in experimentally motivated quantum setups. For a coherently oscillating axion dark matter background\, the induced effective current generates a time dependent magnetic flux in an rf-SQUID\, leading to a measurable voltage signal through the Josephson phase. For representative benchmarks\, this AB phase search reaches the minimum axion-photon coupling g_min ∼ 7.8 × 10^{−14} GeV^{−1} at axion mass m_a ∼ 10−10 eV\, with projected sensitivity that can improve on existing limits in that parameter space by roughly one to two orders of magnitude. We also identify a geometric phase observable in a Mach-Zehnder interferometer with an adiabatically rotating magnetic field\, providing a proof-ofprinciple phase-based probe of meV-scale axions even when they do not constitute the dark matter\, although sensitivity on the coupling remains weaker than current bounds with conservative tabletop benchmarks. Extending the analysis to a three level photon-axion quasiparticle (AQP)-axion system\, with the AQP realized in a topological magnetic insulator\, we find a potentially measurable THz Berry phase dominated by the AQP sector\, furnishing a nontrivial validation of the formalism in a richer coupled system. These setups establish quantum phase observables as a useful new framework for axion searches\, with immediate phenomenological promise in superconducting circuits and longer term potential in quantum enhanced interferometry.\n\nRef: https://arxiv.org/pdf/2604.13181

SUMMARY:Journal Club Event: Renato Fonseca - Formalizing the stability of the two Higgs doublet model potential into Lean: identifying an error in the literature
DESCRIPTION:In 2006\, using the best methods and techniques available at the time\, Maniatis\, von Manteuffel\, Nachtmann and Nagel published a now widely cited paper on the stability of the two Higgs doublet model (2HDM) potential. Twenty years on\, it is now easier to apply the process of formalization into an interactive theorem prover to this work thanks to projects like Mathlib and PhysLib (formerly PhysLean and Lean-QuantumInfo)\, and to ask for a higher standard of mathematical correctness. Doing so has revealed an error in the arguments of this 2006 paper\, invalidating their main theorem on the stability of the 2HDM potential. This case is noteworthy because to the best of our knowledge it is the first non-trivial error in a physics paper found through formalization. It was one of the first papers where formalization was attempted\, which raises the uncomfortable question of how many physics papers would not pass this higher level of scrutiny.\n\nRef: https://arxiv.org/abs/2603.08139

SUMMARY:Journal Club Event: Adrián Moreno Sánchez - Generating the fermion mass hierarchy at the TeV scale
DESCRIPTION:We propose a class of theories to generate quark and lepton mass matrices where the scale of new physics is at the TeV scale\, without inducing the large flavor and CP violating processes that are often thought to relegate the origin of flavor to energies above $\\sim 100$ TeV. The models have new vector-like leptons and quarks\, with mass mixings to each other and Yukawa couplings to light Standard Model fields encoded in "chains" reminiscent of dimensional deconstruction. Locality in the chains both generates the hierarchical Standard Model Yukawa matrices\, and ensures that CP and flavor violating effects are small\, even with the vector-like particles at the TeV scale. A simple extension also generates neutrino masses\, whose tiny size is parametrically related to the square of the electron Yukawa coupling. We outline the essential features of these models\, explain how fermion mass hierarchies and mixing angles emerge\, and explore their phenomenological implications. This framework can be tested both in the final run of the LHC as well as at possible future colliders operating at the 10 TeV scale\, and we identify some of the distinctive experimental signatures associated with the production and decay of the new vector-like fermions.\n\nRef: https://arxiv.org/abs/2602.17754

SUMMARY:Journal Club Event: Chiara Giuliano - Flavour\, Accidentally
DESCRIPTION:We propose a new class of flavour models in which the spurion which breaks Standard Model flavour symmetries transforms in a non-minimal representation. Hierarchies in fermion masses\, which arise from multiple insertions of this spurion\, may be generated in a technically natural\, accidental manner\, from a handful of untuned (1) elements in the UV. This relies explicitly on the non-Abelian nature of the symmetry\, distinguishing it from standard Froggatt-Nielsen-like scenarios. The pattern of flavour violating operators at dimension-6 can radically differ from previously considered scenarios\, and emphasises the need for a broad flavour programme across all generations.\n\nRef: https://arxiv.org/abs/2510.03403

SUMMARY:Journal Club Event: Maria Cristina Fiore - Electroweak ηw meson
DESCRIPTION:We argue that the Standard Model is accompanied by a new pseudo-scalar degree of freedom\, ηw-meson\, which cancels the topological susceptibility of the electroweak vacuum and gets its mass from this effect. The prediction is based on the analyticity properties of the Chern-Simons correlator combined with the basic features of gravity. Depending on the quality level of the U(1)B+L-symmetry\, ηw emerges as a B+L pseudo-Goldstone boson or as a Stückelberg 2-form of the electroweak gauge redundancy. An intriguing scenario of the first category is the emergence of ηw in the form of the phase of a U(1)B+L-violating fermion condensate triggered by the instantons\, somewhat similar to η′-meson in QCD. Regardless of its origin\, the presence of ηw-meson in the theory appears to be a matter of consistency.\n\nRef: https://arxiv.org/abs/2408.07535

SUMMARY:Journal Club Event: Adrián Moreno Sánchez - Imaginary scaling
DESCRIPTION:Recently\, a hitherto unknown class of RG-stable relations between parameters of bosonic field theories have been identified and dubbed as the r0 or 'GOOFy' symmetries. Here\, 1-loop properties of the r0 invariant 2-Higgs Doublet Model and a minimal symmetric model are discussed. It is concluded that the symmetry is present at the 1-loop provided the UV cut-off squared transforms non-trivially under r0. The minimal model requires the presence of two real fields.\n\nRef: https://arxiv.org/abs/2506.21145

SUMMARY:Journal Club Event: Fuensanta Vilches Bravo - 2309.03939
DESCRIPTION:The possible couplings of an axion to gauge fields depend on the global structure of the gauge group. If the Standard Model gauge group is minimal\, or equivalently if fractionally charged color-singlet particles are forbidden\, then the QCD axion's Chern-Simons couplings to photons and gluons obey correlated quantization conditions. Specifically\, the photon coupling can have a fractional part which is a multiple of 1/3\, but which is determined by the gluon coupling. A consequence of this result is that\, among all theories with a minimal gauge group and minimal axion coupling to gluons\, the smallest possible axion-photon amplitude |gaγγ| arises for E/N=8/3. This provides a new motivation for experiments targeting this axion-photon coupling.\n\nRef: https://arxiv.org/abs/2309.03939

SUMMARY:Journal Club Event: Dean Valois - On the extraction of spectral densities from lattice correlators
DESCRIPTION:Hadronic spectral densities are important quantities whose non-perturbative knowledge allows for calculating phenomenologically relevant observables\, such as inclusive hadronic cross-sections and non-leptonic decay-rates. The extraction of spectral densities from lattice correlators is a notoriously difficult problem because lattice simulations are performed in Euclidean time and lattice data are unavoidably affected by statistical and systematic uncertainties. In this paper we present a new method for extracting hadronic spectral densities from lattice correlators. The method allows for choosing a smearing function at the beginning of the procedure and it provides results for the spectral densities smeared with this function together with reliable estimates of the associated uncertainties. The same smearing function can be used in the analysis of correlators obtained on different volumes\, such that the infinite volume limit can be studied in a consistent way. While the method is described by using the language of lattice simulations\, in reality it is completely general and can profitably be used to cope with inverse problems arising in different fields of research.\n\nRef: https://arxiv.org/abs/1903.06476

SUMMARY:Jorge Segovia - 'An introduction to the quark model and its extensions'
URL:https://ftae.ugr.es/index.php/pages/event/course/23
DESCRIPTION:A century of fundamental research in atomic physics has demonstrated that ordinary matter is corpuscular\, with the atoms themselves containing a dense nuclear core composed of protons and neutrons\, collectively named as nucleons\, which are members of a broader class of femtometre-scale particles\, called hadrons. In working towards an understanding of hadrons\, it has been discovered that they are bound states of quarkswhose strong nuclear interactions are described by a Poincaré invariant quantum non-Abelian gauge field theory\, namely\, Quantum Chromodynamics (QCD).A very successful classification scheme for hadrons in terms of their valence quarks and antiquarks was independently proposed by Murray Gell-Mann and George Zweig in 1964. It basically separates hadrons in mesons and baryons which are\, respectively\, quark-antiquark and three-quark bound-states located at the multiplets of the flavor symmetry. The so-called quark model classification received experimental verificationin the late 1960s and\, despite extensive experimental searches\, no unambiguous candidates for other exotic quark-gluon configurations were identified until the beginning of this millennium.The famous X(3872) bump\, discovered in 2003 by the Belle Collaboration\, is just the first of many enigmatic XYZ hadron-like states that have been observed in the last 20 years and whose quantum numbers\, mass and decay patterns do not follow the patterns expected for conventional mesons and baryons. Therefore\, the simplest quark model picture that have been so successful for around 40 years is nowadays challenged\, leading to an explosion of related experimental and theoretical activity.The ultimate aim of theory is to describe the properties of the XYZ states from QCD’s first principles. Since the strong coupling constant becomes large in the energy regime where hadrons live\, perturbative methods are of limited use in QCD.

Starting from the tree-level approximation\, we introduce the BFCW relations and its generalisations\, which allow to compute tree-level amplitude recursively in the number of external legs. Then\, we introduce the method of (generalised) unitarity\, which allow to compute loop-level integrands from lower-order scattering amplitudes.Then\, we consider the problem of integration. First\, we introduce the so-called IBP identities\, to project the integrand into a "minimal" basis of Feynman integrals. The explicit computation of the integrals in the basis is performed using differential equations (DEs)\, in dimensional regularisation. The advantages of DEs relies on the existence of the so called $epsilon$-form\, which allow to express Feynman integrals in terms of iterated integrals in the $epsilon$-expansion. Such integrals are determined up to some boundary conditions which can be fixed requiring the correct analytic properties of the integrals and/or the correct behaviour in particular limits where the computations of the integrals itself is greatly simplified\, using the method of regions.The last part of the lectures is about applications to EFTs\, with a particular focus on gauge theories in four dimensions. We show how to find a basis of EFT interactions from a purely on-shell point of view\, how to compute the renormalisation group equations from scattering amplitudes and how to perform matching giving a specific UV completion.

SUMMARY:Nuno Castro - 'Experimental collider physics and data analysis'
URL:https://ftae.ugr.es/index.php/pages/event/course/15
DESCRIPTION:In these lectures I will cover some key aspects of experimental collider physics\, with focus on the Large Hadron Collider (LHC) at CERN. The basic principles of the particle detection will be discussed and illustrated with concrete examples. Some recent results related to Higgs\, top quark and searches for new phenomena at the LHC will be presented\, and used to discuss how experimental data is acquired\, processed and interpreted. The lectures will also cover topics on statistics and machine learning\, seen as tools for data analysis and interpretation at the LHC
