We present a study of the 3D O(2) non-linear sigma model on the lattice at finite temperature near its second-order phase transition. We consider two disctinct actions: the standard action of this model and a proposed topological action. By analyzing critical exponents and a step-scaling function, we provide evidence that both actions belong to the same universality class. In our study, we investi ... More

Some asymmetries have been reported in $H^\ast\rightarrow ZZ$ decays, which may affect the $Z$ bosons decays to a pair of fermion-antifermion.

We present the consequences of the chiral symmetry restoration within the Yukawa model with spontaneous symmetry breaking. In order to observe chiral restoration, we calculate the effective potential in the high temperature approximation, we take into account one-loop corrections for boson and fermion fields, and ring diagrams correction for boson fields, where the plasma screening properties are ...

At the beginning of 2023, the Mexican government through CONACyT and the Joint Institute for Nuclear Research, JINR (Dubna, Russia) signed a Joint Declaration of Intent for scientific cooperation between the parties. In May of the same year, the installation and kick-off meeting of the Joint Coordination Committee of CONAHCyT and JINR took place. In this talk I summarize the possibilities for scie ... More

La dispersión luz por luz (LbyL), $\gamma\gamma \to \gamma\gamma$, es un proceso raro del modelo estándar (SM) en el que dos fotones interactúan y producen otro par de fotones en el estado final. Este proceso ocurre en el orden más bajo en la electrodinámica cuántica (QED) a través de diagramas de caja virtuales, y está prohibido en la electrodinámica clásica. De manera experimental, se ...

Data from heavy-ion collision experiments such as SPS, AGS and RHIC have shown a sharp peak in the ratio $K^+/\pi^+$ at a value $\sim$ 8 GeV per nucleon, whereas the ratio $K^-/\pi^-$ shows a monotonically increasing behaviour. The energy region in which this phenomenon occurs will be explored by the NICA experiment and is characterized by a high baryonic density. The statistical models predict th ... More

In this talk, we present our work regarding the robustness of the determination of the Dirac CP-phase at several long-baseline experiments: ESSnuSB, T2HKK, and DUNE. The precise determination of the leptonic CP phase is one of the major goals for future neutrino long-baseline experiments. We use the non-standard neutrino interaction (NSI) formalism as a framework. We found that complementarity am ... More

Exotic neutrino interactions arising from heavy new physics have been widely studied and searched for in different neutrino experiments. These can be studied in a model-independent framework by considering all the couplings allowed by the effective field theory (vector, axial, scalar, pseudoscalar, and tensor couplings). In this talk, we will highlight the theoretical motivations for studying s ... More

Ionization detectors based on detecting low-energy nuclear recoils have become an important recent tool to explore neutrino non-standard interactions, direct dark matter searches, etc. For these detectors, the electron ionization efficiency (quenching factor) is relevant to reconstruct the visible energy events. In this study, we present the recent updates to model the quenching factor in pure sil ... More

Precision luminosity measurements are an essential ingredient to cross section measurements at the LHC, needed to determine fundamental parameters of the standard model and to constrain or discover beyond-the-standard-model phenomena. The latest luminosity measurements of the CMS detector at the CERN Large Hadron Collider are reported. The absolute luminosity scale is obtained with beam-separation ... More

We present the 1-loop correction to the correlator of the heavy-heavy quark neutral current for the scalar and pseudoscalar cases. The computation is performed by using the weak magnetic field approximation in the fermion propagator. We show the analytic expression for these corrections at leading order and present their relevance in the context of the QCD Sum Rules at Finite Energy.

The LHC produces a vast sample of top quarks - the heaviest known elementary particles. I will review three measurements in which I had a leading role within the ATLAS Collaboration. The first measurement, chosen as the ATLAS highlight at CERN’s Courier in September 2022, is the most precise measurement of the inclusive top quark pair production cross-section, σ(ttbar), at √s = 5.02 TeV. In a ... More

Hadrons are subatomic particles composed of quarks and gluons bound by the strong interaction. The spectroscopy of hadrons is a challenging and active field of research that aims to understand the properties and structure of these particles. In this contribution, we investigate the ground state and radial excitation masses of hadrons using Bethe-Salpeter equations (BSEs), a non-perturbative appr ... More

A novel method to differentiate the effects of Dirac and Majorana (D-M) neutrinos in four-body decays has been discussed in Phys. Rev. D 105 (2022) 113006. It is concluded in that Ref. that the back-to-back kinematic scenario seems to avoid the constraint imposed by the ‘practical Dirac-Majorana confusion theorem’ as one does not need to fully integrate over neutrino and antineutrino momenta. ...

Nowadays, experimental neutrino physics is going through an exciting moment due to the high-precision measurements, in huge detectors, expected from experiments to come, e.g. DUNE. At Fermilab in Chicago, Illinois there is a Short-Baseline Neutrino program (SBN) searching for sterile neutrino signatures. This program consists of three detectors that use the liquid argon time projection chamber tec ... More

Tensor dark matter (TDM) is a recently explored proposal for describing dark matter (DM) as a spin-one field in the $(1,0) \oplus (0,1)$ representation of the homogeneous Lorentz group. In this work, we study the renormalization of the U(1) gauge theory for TDM at the one-loop level in the MS scheme. The interaction is found to be non-renormalizable due to the bad behavior of the TDM propagator in ... More

The presentation of this work focuses on the adjustment to the efficiency of a double b tagger that identifies a fat jet resulting from the decay of the dark Higgs boson by scale factors in the context of dark matter searches, specifically using the dark Higgs model. Scale factors are calculated by applying the tagger in jets of a b quark enriched sample from data from LHC Run 2 and Monte Carlo si ... More

The search for exotic hadrons has overgrown since the first observation by the Belle collaboration in 2003, when observed a like-resonant structure in the exclusive decay B → X^{0}K → (J/ψπ^{+}π^{-})K. This state X does not match with the known charmonium states and the possibility of being an exotic state was considered. Its charged partner was searched in X^{-} → J/ψπ^{-}π^{0} but no ... More

We present a study of the 2- and 3-dimensional O(2) model, or XY model, out of equilibrium through Monte Carlo simulations. In particular, we analyze the dynamics of the topological defects of the system (vortices) when we linearly lower the temperature at various cooling rates, starting above the critical temperature, $T_c$, down to $T < T_c$. We test Zurek's prediction for the scaling behavior o ... More

The Scotogenic model is a popular scenario that induces radiative Majorana neutrino masses and includes a weakly-interacting dark matter candidate. We classify all possible ultraviolet extensions of the Scotogenic model in which (i) the \textit{dark} $\mathbb{Z}_2$ parity emerges at low energies after the spontaneous breaking of a global $\rm U(1)_L$ lepton number symmetry, and (ii) the low-e ...
