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: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.

DESCRIPTION:Quantum computing provides a promising framework for simulating strongly coupled gauge theories relevant to high-energy physics. In this talk\, I will discuss quantum simulations of lattice gauge theories\, focusing on the Schwinger model as a benchmark Abelian system and on a non-Abelian SO(3) gauge theory formulated as a quantum link model. I will outline gauge-invariant encodings and circuit implementations suitable for near-term devices\, and comment on prospects for using quantum algorithms to study real-time dynamics and other regimes challenging for classical methods.

SUMMARY:Carlos Duaso Pueyo - 'Aspects of effective field theories in expanding spacetimes'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/443
DESCRIPTION:EFTs have become indispensable tools in cosmology\, yet most of our intuition about them comes from their formulation in flat space. In this talk we explore two aspects in which this Minkowski-based intuition fails and suggest ways to address these limitations. The first aspect is perturbative unitarity bounds\, which tell us when perturbation theory breaks down. In flat space\, such bounds can be obtained from partial wave decomposition of amplitudes\, but scattering experiments are difficult to define in curved spacetimes. We propose to use the growth of entanglement as a breakdown diagnostic for perturbation theory—this diagnostic can be readily used in general spacetimes and does not require taking any flat spacetime limit. The second aspect is the EFT derivative expansion. In cosmology this expansion is asymptotic rather than convergent\, due to the fact that the contribution of operators with mass dimension ∆ to physical observables grows factorially with ∆. We show through a couple of simple toy models that meaningful EFT predictions can still be extracted via appropriate resummation techniques.

SUMMARY:Ludovic Scyboz - 'How to turn one parton into many (accurately)'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/440
DESCRIPTION:Monte Carlo (MC) generators have been used extensively for the past decades in order to simulate collisions at particle colliders\, like the LHC. These tools are often misconstrued as a semi-careless medley of ingredients. Their core component\, the parton shower\, is responsible for generating the extra partonic radiation that we observe\, from the high energies of the hard scattering down to the hadronisation scale. For a long time\, it was unclear what accuracy\, in the sense of perturbative QCD\, was associated with this part of the simulation: in this talk I will recap how modern MC generators operate\, focusing on their parton-shower component. I will present recent breakthroughs in the development of more precise showers\, and the ways we test these tools rigorously.

SUMMARY:Eduardo Garnacho-Velasco - 'Effect of QED interactions in the thermodynamics of QCD from the lattice'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/439
DESCRIPTION:The study of QED corrections to observables in QCD is by now well-understood at zero temperature\, where it has been extensively studied and developed by the lattice QCD community. In this setup\, QED effects are perturbative and are required to study precision physics observables\, such as the neutron-proton mass difference or the muon g-2\, among many others. However\, there are indications that at finite temperature the introduction of QED can lead to non-perturbative effects\, potentially affecting the structure of the phase diagram. In this talk\, we will first review the basic aspects of lattice gauge theory and of the thermodynamics of QCD\, focusing on the role played by the symmetries of the theory. We will then motivate the study of QED effects in the phase diagram of QCD\, analyzing the symmetries of the combined theory and its possible consequences for the phase transitions. We will continue by presenting novel results of lattice QCD+QED simulations at finite temperature\, focusing on understanding the role of the electromagnetic coupling in the thermodynamics of this system. We will also analyze some new properties that arise in the combined theory and the challenges that these simulations entail\, as well as the new directions we are currently developing to understand the phase diagram of QCD+QED from first principles.

SUMMARY:Filippo Sala - 'High energy neutrinos from dark matter around blazars'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/438
DESCRIPTION:The nature of dark matter (DM) and of the sources of observed high-energy neutrinos are two major open questions of fundamental physics and astrophysics. I will show how they could have a common answer by proving that inelastic scatterings\, between sub-GeV DM around super-massive black holes and protons within their jets\, could explain neutrinos observed from single blazars\, like TXS 0506+056\, as well as IceCube's diffuse neutrinos above 100 TeV. I will prove that this proposal is compatible with all laboratory\, direct and indirect searches for light DM and identify its most promising future tests. I will finally discuss prospects for handling the important uncertainties affecting DM around blazars\, like those on the DM density distribution and on the blazar jet modelling.

SUMMARY:Lorenzo De Ros - 'Non-Relativistic Effective Field Theories for Dark Matter with Long-Range Forces'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/437
DESCRIPTION:Effective field theories provide a systematic framework to describe non-relativistic systems.Dark matter in the early Universe and in present-day halos is non-relativistic\, and its relic abundance and indirect detection signals are controlled by annihilation rates.Non-relativistic effective field theories offer a framework where such rates can be computed systematically.They also consistently account for long-range interactions\, such as Coulomb-like potentials\, that arise in models with light mediators.Radiative processes\, including bound-state formation\, can be incorporated within the same framework and can significantly impact the phenomenology.As an explicit example\, I will discuss a colour–flavour locked self-interacting dark matter model that can also address small-scale structure tensions.

URL:https://ftae.ugr.es/index.php/pages/event/seminar/436
DESCRIPTION:We discuss an AI-assisted inference pipeline that learns the mapping between Wilson coefficient deformations and collider observables directly from simulated event data. This approach constructs physics informed latent representations of SMEFT parameter space using neural architectures trained on differential cross sections and kinematic distributions. These learned embeddings enable efficient anomaly detection\, parameter discrimination\, and dimensionality reduction while preserving sensitivity to interference effects and operator correlations. We demonstrate how the framework accelerates likelihood-free inference\, improves separation between Standard Model and BSM hypotheses\, and provides interpretable structure in the space of EFT deformations.

SUMMARY:Marco Piva - 'Ghost-free renormalizable gravity from purely virtual particles'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/434
DESCRIPTION:Quadratic gravity offers a compelling path to a renormalizable quantum theory of gravitational interactions. However\, renormalizability comes at the price of unitarity\, which is violated by the presence of ghosts\, undermining its physical viability. Purely virtual particles (PVP) provide a solution to this problem. They are novel degrees of freedom that can mediate interactions without ever appearing as on-shell states\, allowing quadratic gravity to preserve its ultraviolet behavior while restoring unitarity. After reviewing the nonrenormalizability of Einstein gravity\, I will show the relation between renormalizability and unitarity violation in quadratic gravity and explain how PVP can be consistently incorporated into general quantum field theories. Finally\, I will discuss potential observable imprints of PVP in  inflationary cosmology\, as well as in particle physics.

SUMMARY:Daniel González-Cuadra - 'Quantum simulation of lattice gauge theories with Rydberg atom arrays'
URL:https://ftae.ugr.es/index.php/pages/event/seminar/433
DESCRIPTION:Lattice gauge theories (LGTs) describe a broad range of phenomena in condensed matter and particle physics. A prominent example is confinement\, responsible for bounding quarks inside hadrons such as protons or neutrons. When quark-antiquark pairs are separated\, the energy stored in the string of gluon fields connecting them grows linearly with their distance\, until there is enough energy to create new pairs from the vacuum and break the string. While such phenomena are ubiquitous in LGTs and play a prominent role in particle-physics experiments\, simulating the resulting dynamics is a challenging task. In this talk\, I will report the observation of string breaking using a programmable quantum simulator based on neutral atom arrays [Nature 642\, 321–326 (2025)]. I will first show how a (2+1)D LGT with dynamical matter can be efficiently encoded using a system of Rydberg atoms\, where a U(1) gauge symmetry emerges from the Rydberg blockade mechanism\, while long-range Rydberg interactions naturally give rise to a linear confining potential between pairs of charges. In the experiment\, we probe string breaking in equilibrium by adiabatically preparing the ground state of the atom array in the presence of defects\, distinguishing regions within the confined phase dominated by fluctuating strings or by broken string configurations. Finally\, by harnessing local control over the atomic detuning\, we quench string states and observe string breaking dynamics exhibiting a many-body resonance phenomenon. As an outlook\, I will present a roadmap to further explore phenomena in high-energy physics using programmable quantum simulators.

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

DESCRIPTION:Single-minus tree-level $n$-gluon scattering amplitudes are reconsidered. Often presumed to vanish\, they are shown here to be nonvanishing for certain "half-collinear" configurations existing in Klein space or for complexified momenta. We derive a piecewise-constant closed-form expression for the decay of a single minus-helicity gluon into $n-1$ plus-helicity gluons as a function of their momenta. This formula nontrivially satisfies multiple consistency conditions including Weinberg's soft theorem.\n\nRef: https://arxiv.org/abs/2602.12176

SUMMARY:Journal Club Event: Andrea Sanfilippo - De Sitter Momentum Space
DESCRIPTION:Single-minus tree-level $n$-gluon scattering amplitudes are reconsidered. Often presumed to vanish\, they are shown here to be nonvanishing for certain "half-collinear" configurations existing in Klein space or for complexified momenta. We derive a piecewise-constant closed-form expression for the decay of a single minus-helicity gluon into $n-1$ plus-helicity gluons as a function of their momenta. This formula nontrivially satisfies multiple consistency conditions including Weinberg's soft theorem.\n\nRef: https://arxiv.org/abs/2602.12176

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: Roberto Vega-Morales - Schwinger effect in de Sitter space
DESCRIPTION:In this blackboard talk I will give a short and basic review of the Schwinger effect in de Sitter space which has potential applications in magnetogenesis and dark matter production. In particular I will go through calculations of the de Sitter Schwinger current performed in recent years which exhibited some puzzling (un-physical) behavior. I will then discuss how our recent work seeks to remedy these puzzling features and future directions of investigation. This will be based on the following papers:\n\nhttps://arxiv.org/abs/1408.4141\nhttps://arxiv.org/abs/1603.04165\nhttps://arxiv.org/abs/2508.14973\n\nRef: https://arxiv.org/abs/2508.14973

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:Journal Club Event: Alba Soto Ontoso - News from the light ion runs at the LHC
DESCRIPTION:For the first time\, the CMS experiment has measured how particles flow in collisions of oxygen-oxygen (OO) and neon-neon (NeNe) ions at the Large Hadron Collider (LHC). These small\, but powerful\, collisions reveal clear signs of collective behavior\, similar to what is seen in much larger systems such as lead-lead (PbPb) collisions. The results provide robust evidence for how the initial geometry of colliding nuclei translates into final particle flow – a key step toward understanding collectivity in small collision systems and its possible connection to a hot and exotic state of matter called the quark-gluon plasma (QGP).\n\nRef: https://cms.cern/news/collective-motion-tiny-systems-oxygen-and-neon-collisions-window-nuclear-structure

SUMMARY:Journal Club Event: Luis Gil Martín - Domain walls seeding the electroweak phase transition
DESCRIPTION:Topological defects can act as local impurities that seed cosmological phase transitions. In this paper we study the case of domain walls\, and how they can affect the electroweak phase transition in the Standard Model extended with a Z2-odd scalar singlet. When the transition is two-step\, the early breaking of the Z2 symmetry implies the formation of domain walls which can then act as nucleation sites for the second step. We develop a method based on dimensional reduction to calculate the rate of the catalyzed phase transition within the 3d theory on the domain wall surface. By comparison with the standard homogeneous rate\, we conclude that the seeded phase transition is generically faster and it ultimately determines the way the phase transition is completed. We comment on the phenomenological implications for gravitational waves and baryogenesis.\n\nRef: https://arxiv.org/abs/2203.16450

SUMMARY:Journal Club Event: Mikael Chala - What is the source of the PTA GW signal?
DESCRIPTION:The most conservative interpretation of the nHz stochastic gravitational wave background (SGWB) discovered by NANOGrav and other pulsar timing array (PTA) collaborations is astrophysical\, namely that it originates from supermassive black hole (SMBH) binaries. However\, alternative cosmological models have been proposed\, including cosmic strings\, phase transitions\, domain walls\, primordial fluctuations\, and “audible” axions. We perform a multimodel analysis (MMA) to compare how well these different hypotheses fit the NANOGrav data\, both in isolation and in combination with SMBH binaries\, and address the questions: Which interpretations fit the data best\, and which are disfavored? We also discuss experimental signatures that can help discriminate between different sources of the PTA GW signal\, including fluctuations in the signal strength between frequency bins\, individual sources\, and how the PTA signal extends to higher frequencies.\n\nRef: https://arxiv.org/pdf/2308.08546

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.

SUMMARY:Stefano De Angelis - 'Lectures on Scattering Amplitudes and EFTs'
URL:https://ftae.ugr.es/index.php/pages/event/course/16
DESCRIPTION:The lectures will cover a general introduction to modern on-shell techniques to compute perturbative scattering amplitudes (and form factors).I will start from a broad introduction to the S-matrix and its perturbative (and some non-perturbative) properties. 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.
