Type: Conference Session: Current progress in the muon g-2
The anomalous magnetic moment of the muon is an interesting quantity to search for new physics. In particular, it has attracted quite attention due to the persisting discrepancy among theory and experiment, that has been confirmed recently this year at Fermilab. This talk reviews the essential concepts surrounding g-2 at a basic level, discussing the current progress and state of the art. Specia ... More

Type: Conference Session: Session. Hadrons and QCD 1
The global polarization of $\Lambda$ and $\bar{\Lambda}$ has recently become a topic of great interest because it has been associated with the properties of the medium produced in relativistic heavy ion collisions. It has been studied the possibility that the global vorticity, produced in semi-central collisions, be estimated in terms of global polarization, since this is transferred to the degree ... More

Type: Conference Session: Plenary Talk (Rodolfo Ferro)
In this talk I will discuss with an introductory approach the NLO and NNLO corrections to the Electroweak sector of the Standard Model. Then I will explain how the weak mixing angle at low energies is computed.

Type: Conference Session: Plenary Talk (Raymundo Ramos)
In this talk we will discuss a precise calculation of the relic density and temperature evolution of dark matter (DM) including effects from three different sectors: DM sector, light scalar mediator sector and standard model (SM) sector. We derive a set of four coupled Boltzmann equations in the context of a Majorana fermion dark matter model where DM communicates with the SM via a light sca ... More

Presented by Norma Selomit RAMÍREZ URIBE on 9 Aug 2021 at 13:00
In this talk, we will discuss about recent developments concerning efficient calculations of multi-loop multi-leg scattering amplitudes. Inspired by the nice properties of the Loop-Tree Duality (LTD), we explain how to reconstruct an integrand level representation of scattering amplitudes which only contains physical singularities. The so-called causal representations can be originated from connec ... More

Type: Conference Session: Gravity as the square of gauge theory
The BCJ double copy relates scattering amplitudes in gauge and gravity theories by means of a squaring procedure. This connection has shown to be deeper, extending also to classical systems. In this talk I will review the basics of the double copy, as well as some recent developments.
Presented by Mr. Luna ANDRES on 12 Aug 2021 at 08:50
In this talk I will give an overview on recent results on the spectrum and properties of conventional and exotic hadrons as obtained in the framework of Dyson-Schwinger and Bethe-Salpeter equations. Particular emphasis is given on a pedagogical introduction into the method. I will discuss strategies of approximating QCD and present resulting spectra of mesons, baryons, glueballs and four-q ...

Presented by Dr. Tomás CAPISTRÁN on 11 Aug 2021 at 11:25
We study the neutrinoless double beta decays of hyperons triggered by an effective one loop mechanism involving baryons and Majorana neutrinos as intermediate states. We provide a reliable estimation of their maximum branching fractions by assuming a reasonable momentum dependence for the hadronic transition form factors in the loop integral. We explore two interesting scenarios compatible with th ... More

Type: Conference Session: Physics of the Tau Lepton
I will provide a short overview on the most relevant physics that involves the tau lepton. The lecture will be divided along the following lines: 1) General features of tau lepton decays; 2) Leptonic decays; 3) Inclusive hadron decays; 4) Exclusive hadron decays; 5) Breaking the rules of the Standard Model. Although the lecture will focus on the processes allowed by the Standard Model we will also ... More

Type: Conference Session: Plenary Talk (Alexis D. Plascencia)
I will discuss unique relations between the decay widths for leptoquarks and Higgs bosons that can be used to test the unification of quarks and leptons at the TeV scale. I will present the main predictions of the minimal theory for quark-lepton unification and show how the different decays for leptoquarks and Higgses are related by the symmetry of the theory. I will further comment on the possibi ... More
Presented by Alexis PLASCENCIA on 10 Aug 2021 at 12:30
I will discuss the quantisation of a Klein-Gordon field in a region with boundary with dynamical boundary conditions, which are prescribed by a boundary field equation. I then define the local energy of the field, which allows one to study the Casimir effect in this model at zero and finite temperatures, as well as in coherent states. I will emphasise on the physical perspectives and relevance of ... More
Presented by Dr. Benito A JUÁREZ AUBRY
Confirming or ruling out the existence of deconfined quark matter inside neutron stars is one of the most prominent open problems in nuclear astrophysics. While the ultimate goal continues to be the observation of a smoking gun signal directly indicating the presence or creation of quark matter, a more indirect approach to the problem has lately become feasible. By combining ab-initio theoretical ... More

Type: Conference Session: Session. Hadrons and QCD 1
In recent years our understanding of the equation of state (EoS) of dense nuclear matter has been significantly improved by the analysis of multimessenger data from gravitational wave and radio and X-ray pulsars. The interpretation of such data established important constraints for physical observables as maximum mass, radius, and tidal deformability of a neutron star inspiral: to describe dense m ... More

Type: Conference Session: Session. Hadrons and QCD 1
Recently, powerful quantum field theory techniques, originally developed to calculate observables in colliders, have been applied to describe classical observables relevant to gravitational wave physics. One of these techniques is the double copy, which suggests that the basis of the dynamics of general relativity is Yang-Mills theory. In this talk, I will first give a brief review of the framewo ...

Type: Conference Session: Session. Hadrons and QCD 1
We provide an overview over Transverse Momentum Dependent (TMD) Parton Distribution Functions (PDFs). While we will also comment on TMD PDFs in general, we will focus on their use for the description of hadronic reactions in the so-called low x limit. Here $x = M^2/s$ and $M$ is the hard scale of the process, while $\sqrt{s}$ is the center of mass energy of the reaction. We will explain why this a ... More

Neutrino Astronomy allows us to observe the distant, high-energy universe. It was born when the IceCube experiment reported the first observation of neutrinos with energies in the PeV regime. Neutrinos with higher energies, called ultra-high energy (UHE) neutrinos, are predicted to exist, but they have not been observed yet due to their extremely low flux, requiring immense detection volume. An al ... More

Type: Conference Session: Plenary Talk 3 (Maura E. Ramirez-Quezada)
We discuss the capture of dark matter in white dwarfs (WD), the most abundant stellar remnants, as complementary to terrestrial searches. We consider the capture of DM due to interactions with either ion or the degenerate electron component of WDs. We account for the stellar structure, star opacity, realistic nuclear form factors, and temperature effects to discuss the capture rate. In the case of ... More
