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

Neutrinos, fundamental particles with extremely small masses, exhibit unique properties such as flavor oscillation and weak interaction with ordinary matter, which makes their detection challenging. This has led to the development of large-volume detectors, such as ultrapure water tanks equipped with photosensitive sensors capable of registering Cherenkov radiation. On the other hand, supernovae

Measurements of long-range azimuthal correlations and strangeness enhancement in small systems such as pp and p--Pb collisions have revealed features reminiscent of nucleus--nucleus interactions, raising the question of whether genuine QGP droplets are formed. In this work, we study jet--medium interactions at $\sqrt{s_{\mathrm{NN}}} = 5.02$ TeV by analyzing particle production with respect to the

In this work, we propose a methodology to quantify the production of softened hadrons in pp, pA, and AA collisions at LHC energies, as well as their contribution to the $p_T$ spectrum, effective temperature, and mean $p_T$. Within the color string fragmentation framework, we describe the charged particle production through the Tricomi function, resulting from the convolution of the Schwinger mecha

The detection of cosmic rays, and of ionizing radiation in general, is commonly carried out using ionizable materials —where ions are produced— and photonizable materials —where photons are produced—; from these materials, radiation detectors are built. Because of this, practically any material can be used to detect ionizing radiation.
In this talk, we present the planning, design, constr

I will describe how classical gravitational dynamics is extracted from quantum scattering amplitudes. I will explain how QFT tools are applied to the binary black hole inspiral problem.

In this talk, we discuss how isospin-violating dark matter—particles that couple differently to protons and neutrons—affects the so-called neutrino fog, the irreducible background in direct detection experiments. We explore under which conditions this background can be mitigated for certain dark matter models.

Even though photomultiplier tubes technology is turning more than a century, it is still used with many advantages over recent solid-state technology like SiPM, with many applications in medicine, oil exploration, lidar communication, astrophysics, high energy physics, cosmic ray detection, etc. For cosmic ray detection and astrophysics applications, we designed, constructed, characterized, and ap

In this work, I present research focused on the development of the Muon Identifier (MID) detector for the proposed ALICE-3 experiment at CERN — a key component for advancing the study of heavy-ion collisions at the LHC. The study centers on the design, construction, and optimization of a 1 × 1 m² MID prototype chamber, composed of 40 plastic scintillator bars, each measuring 5 × 100 × 1 cm³

We explore a dark matter model with a non-minimal coupling to gravity that enables decay into Standard Model particles. Using CLUMPY, we analyzed gamma-ray and neutrino fluxes from fourteen dwarf spheroidal galaxies, studying the impact of varying dark matter mass and the coupling parameter. Including neutrino oscillations allows us to estimate the detectable neutrino flux on Earth, providing pros

This research explores the viability of the DarkBS model, an extension of the Standard Model (SM) designed to address the mystery of Dark Matter (DM). The model proposes a WIMP candidate and a new mediator boson, 𝑍′. We constrain the model parameters using a phenomenological approach, numerically computing limits on the DM relic abundance, bounds imposed by Direct Detection (DD) experiments,

We study the one-loop renormalization of massless matter fields in the $(1,0)\oplus(0,1)$ representation of the Restricted Lorentz Group. The model is constructed with the most general parity-invariant kinetic term and includes all the independent dimension-4 parity-invariant self-interactions available in this representation. Its free Lagrangian reproduces the massless limit of three theories pre

Kinematic reconstruction and particle identification in water-Cherenkov detectors are typically performed with maximum-likelihood methods such as fiTQun. We assess deep neural networks as an alternative for e−/mu− separation and kinematic reconstruction. Using particle-gun simulations of electrons and muons generated with WCSim v1.12.19 for the IWCD detector, we trained on fully contained even

ABSTRACT:
Since the discovery of cosmic rays, they have been of great scientific interest -such as searching for components, energy spectrum, astro physic sources, origin, and the way to detect and study them-. To accomplish these activities, a vast variety of detectors have been designed and operated. We have planned, designed, constructed, characterized and operated a small two channel cosmic r

In this work we extend a previous analysis of $\tau\to KK\pi\nu_\tau$ decays to include all possible tau decays into three I$\ne$0 mesons using Resonance Chiral Theory. We constrain the couplings in the Lagrangian by imposing the high energy behaviour of the form factors. We reproduce results from the previous work, namely in the $KK\pi$ channel.

The following calculations extend the results of the paper published on 1992 by
K¨uhn and Mirkes (K&M), for the particular case of interference between an
antisymmetric tensor and one (axial-)vector current.
The KM analysis was based on a formalism designedto systematically handle reactions of the type τ → h1h2h3ντ , for h_{1,2,3} being any meson in the lighter SU(3) flavour octet, by co

Luminosity measures the density of collisions at the LHC and is a key parameter for both physics analyses and accelerator operations. Its calibration is performed annually through a series of scans called the Van der Meer program (VdM). This project presents a preliminary analysis of the variable length scale scan, from the 2024 VdM program. The main goal is to determine the correction to the lumi

We calculate the neutrino-electron elastic scattering cross section in the presence of generic new interactions that take into account all the effects caused by finite neutrino masses. We address the potential significance of a heavy neutrino sector during precision measurements and comment on the possibility to distinguish between Dirac and Majorana neutrinos.
We realized a phenomenological study of top-antitop production in the environment of CERN's Compact Linear Collider project in its third stage. We followed the approach of Standard Model Effective Filed Theory (SMEFT), using the Warsaw basis for the set of mass-dimension 6 operators. From this basis, we analyzed separately the five operators that generate contributions at tree-level to the process
