Plastic scintillators are versatile revealing media for radiation detection and find applications in a wide range such as homeland security, environmental assays, radioprotection or personal dosimetry. Their composition and size are key parameters that define how a type of radiation can be detected and determine some characteristics of the pulse produced by the pass-through radiation. In this work

A Resistive Plate Chamber (RPC) is a type of ionizing particle detector that uses a gas mixture as the active detection medium and is characterized by its fast time response. One of the key parameters defining its operating characteristics is the separation distance between the resistive plates that make up the detector, known as the GAP.
Based on a methodological study, two resistive plate det

We explore the sensitivity of the $e^{+} e^{-} \to K^+ K^- 2 \pi^0$ cross section to the magnetic dipole moment (MDM) of the $K^*$ vector meson. We describe the $\gamma^* \to 2K2\pi$ vertex using a vector meson dominance model, including the intermediate resonant contributions relevant for energies below 2.4 GeV. Using BaBar data for this process, we show that this observable is indeed sensitive t

Los modelos con extensiones del sector de higgs, como el 2HDM y el MSSM, predicen la existencia de un bosón pseudoescalar A_p (CP-impar) cuyas propiedades están relacionadas con las fuentes de violación de CP. En esta plática se presenta un estudio fenomenológico de la búsqueda de un A_p producido por fusión de gluones y decayendo A_p -> Zh, con Z -> l+ l- y h->tau_h tau_h, Mediante un

In high-energy proton-proton (pp) collisions, the transverse momentum (pT) spectrum of produced particles exhibits two characteristic regimes: a soft region at low pT, commonly described by statistical models, and a hard region at high pT, associated with perturbative Quantum Chromodynamics.
The pT region where the soft description begins to break down and the transition toward hard processes t

The Front-End based on the PETIROC2A ASIC has 32 independent channels and was originally designed for the readout of SiPM detectors. Its use is being considered as a proposal for the data acquisition electronics of the Muon ID subsystem in ALICE 3. Each channel incorporates fast preamplifiers, programmable discriminators, as well as circuits that allow both charge and time measurements with a temp

Sensibility to radiative corrections of the $WW\gamma^*$ and $WWZ^*$ vertices emerging from the extra-dimensional standard model's bosonic Kaluza-Kleins excitations is studied. This takes place in the universal extra dimensional proposal. This extension of the standard model does not rest in the enlargement of the gauge group, but rather in the enlargement of the Poncaré group of the theory. The

This work investigates the geometrical optimization of the Muon Identifier (MID) to maximize particle acceptance using Monte Carlo simulations implemented in ROOT. A simplified detector model is employed to study the effects of module orientation and spacing on geometrical acceptance. Systematic scans of transverse tilt, longitudinal inclination, and inter-ring distance are performed to identify f

This work investigates the phenomenology of a vector dark matter model based on an additional hidden gauge symmetry, (SU(2){HS}), introduced through a scalar doublet (\Phi). The scalar potential exhibits a global (SO(4)) symmetry, which is spontaneously broken by the vacuum expectation value of (\Phi), giving mass to the new gauge bosons (A\mu^i). The resulting custodial (SO(3)) symmetry ensures t

This work investigates Higgs boson decays into invisible particles within extensions of the Standard Model featuring a new (U_D(1)) gauge symmetry associated with a massless dark photon. Two theoretical frameworks are considered: one involving fermionic mediators and another involving scalar mediators. Using one-loop amplitude calculations, several decay channels are studied, and their viability i

We describe an ongoing analysis performed with the CMS experiment, studying decays of the heavy flavor baryon $\Xi^{-}_b$. The main result is the measurement of the branching fraction of $\Xi^{-}_b \to \Xi^{-} \psi(2S)$ relative to the normalization channel $\Xi^{-}_b \to \Xi^{-} J/\psi$, achieved with improved precision compared to previous measurements. The previous measurement of this ratio was

We study the charged particle production in ultrarelativistic collisions within the color string fragmentation picture. In this picture, we describe the $p_T$ spectrum as the convolution of the Schwinger mechanism with string tension fluctuations. Importantly, reproducing the power-law tail of the experimental $p_T$ spectrum requires heavy-tailed distributions. For instance, the recently introduce

Higgs pair production via gluon fusion, $gg \to HH$, probes the Higgs trilinear self-coupling and is loop-induced already at leading order, which makes it sensitive to new colored states. We study the one-loop effects of the scalar leptoquark $S_{1} \sim(\bar{3},1,1/3)$, including its full yukawa sector and a Higgs portal coupling $\lambda_{S_{1H}}|H|^2|S_1|^2$. We implement the model in FeynRules

Recent experimental measurements at the LHC suggest the possible existence of a spin-0 particle with a mass different from that of the Higgs boson, motivating extensions of the Standard Model with an enlarged Higgs sector. In such models, the scalar sector typically contains five physical particles, including a pseudoscalar state $A$.
In this work, we use experimental constraints from the CMS C

The high-luminosity phase of the LHC will provide new opportunities to probe Higgs couplings to gauge bosons and search for deviations from Standard Model predictions. In this work, we investigate new physics effects in the $HWW$, $HZZ$, and $HZ\gamma$ couplings, with particular emphasis on observables sensitive to their $CP$-odd form factors and their potential measurement at the LHC. We also exp

I will present the calculation of the propagator of a charged vector boson in the presence of an external magnetic field using the Ritus Eigenfunction method. Although this is not a novel result, the methodology used throughout the calculation is relevant in the sense that the calculation is done with a diagonalized equation of motion.
Moreover, I present the path from the propagator in the Rit

The MuonID detector at ALICE3 at CERN, designed to identify muons beyond the 70-cm absorber and operate in triggerless mode, requires electronic systems capable of handling up to 6,400 channels with high granularity (50–60 mm/pad). In this context, simulation of the lpGBT chip is essential for validating the new Front-End Card (FEC), ensuring high-speed optical links of up to 10 Gb/s, low latenc

In a previous study, simulations were performed to evaluate the feasibility of antineutron ($\bar{n}$) identification and kinematic reconstruction via hadronic charge-exchange (CEX) interactions: $\bar{n}+n\rightarrow\bar{p}+p$ and $\bar{n}+n\rightarrow\bar{p}+p+\pi^0$. The target neutrons are those in the silicon nuclei of the inner tracking detectors used in LHC experiments such as ALICE, ATLAS,

We describe the $\omega\pi$ spectral function, measured in the decay
$\tau^- \to \pi^-\omega\nu_\tau$ by the CLEO Collaboration, using an
importance sampling procedure to explicitly account for the correlation
between the parameters of the corresponding form factor. We exhibit the
improvement in the uncertainties, compared to the uncorrelated case, and
show the agreement with the expected fro

The study of four-top-quark production, $t\bar{t}t\bar{t}$, constitutes an important tool in the search for signals of new physics, due to its sensitivity to possible deviations from the predictions made within the Standard Model, particularly in the heavy-particle and Higgs sectors. To exploit this sensitivity, a precise description of the Standard Model processes that can imitate (background) th
