The $\tau^- \to \pi^-\eta\nu_{\tau}$ decay is forbidden in the Standard Model in the limit of exact $G$-parity, it becomes a rare decay due to isospin symmetry breaking and it is very sensitive to the effects of effective scalar interactions. Since the parameters driving isospin breaking, $(m_d-m_u)/(m_s-\bar{m})$ and $\alpha$, are of the same order, one may expect their $G$-parity breaking effect

In the present work, the conversion of charge to time is studied for the characterisation of an RPC type gaseous detector. For this purpose, a 32-channel front-end ASIC, the WEEROC PETIROC2A board, was characterised and calibrated. Using an array of four detectors, two RPCs each with four panels and two plastic scintillators together with their respective PMTs, the latter being used as external tr

The search for dark matter particles at the LHC is one of its primary objectives. Well-motivated scenarios, such as the Hidden Abelian Higgs Model (HAHM) and Dark Supersymmetry (Dark-SUSY) scenarios predict the production of dark sector particles. These particles interact weakly with the Standard Model (SM) and, due to their interactions, can decay into SM particles. A key signature of these searc

Vector mesons possess 2s+1 electromagnetic properties (where s=1 is their spin). Specifically, these are the electric charge, the magnetic dipole moment (MDM), and the electric quadrupole moment (EQM). Among these, only the electric charge is experimentally well-determined due to charge conservation laws; the remaining multipoles are merely estimated using effective QCD models, for which no experi

Ultra-peripheral collisions (UPCs) serve as a powerful tool to investigate the strong interaction in high-energy regimes through the exclusive photoproduction of vector mesons. In this work, we focus on the production of the vector meson J/ψ in Pb–Pb and Pb–p collisions, using data reported by the ALICE and CMS collaborations. We explore whether the energy dependence of the production cross s

We start by reproducing the results in the literature of leptonic decays of muon and tau leptons using the most general four-lepton effective interaction of dimension six. First, working in the decaying-lepton rest frame, we calculate the final charged-lepton distribution while incorporating the effects of the initial charged lepton polarization. We review the new generalized Michel parameters in

We use the linear sigma model with quarks to study the magnetic-field-induced modifications on the longitudinal and transverse screening masses for the neutral pion at one-loop level. The effects of the magnetic field are introduced into the self-energy, which contains the contributions from all the model particles.

In this work, we analyze a non-minimal SUSY $SU(5)$ model extended with an $S_3$ modular flavor symmetry, a Higgs sector containing six electroweak doublets, and right-handed neutrinos (RHNs) as singlets under the gauge symmetry.

In string models, the production of charged particles can be described by the convolution of the Schwinger mechanism with string tension fluctuations, usually modeled as a Gaussian distribution. However, by incorporating $q$-Gaussian string tension fluctuations, we can fully describe the $p_T$-spectrum of charged particles produced in pp collisions obtaining Tricomi’s function, which captures bo

Recently, the canonical quantization of massive spin-1/2 fermions obeying Klein-Gordon like dynamics has been shown to become consistent by introducing a redefinition of the dual field that renders the theory pseudohermitian.
