Protons and neutrons are among the basic building blocks of ordinary matter and account for more than 99% of the mass of the visible universe. They have been discovered about a century ago and, since then, their properties and composition have been studied both theoretically and experimentally with an increasing level of precision and accuracy. With the advent of the quark model and of QCD...
The study of the mass spectra as well as the decay properties of single bottom baryons is relevant in hadron physics. Until now, only a few single bottom baryons have been discovered and many of them have to be discovered in the future. In this work, we computed the mass spectra of single bottom baryons within the quark model formalism up to $D$-wave states. Additionally, we calculated the...
In hadronic collisions, charm and beauty quarks are mainly produced in hard partonic scatterings due to their large masses, $m_{\text{c}}=$ 1.3 $ \text{GeV}/c^2$ and $m_{\text{b}} =$ 4.1 $ \text{GeV}/c^2$. They are ideal tools to investigate various aspects of perturbative QCD.
In addition, measurements in pp collisions represent a baseline for cold nuclear matter studies in p--A...
Generative models driven by artificial intelligence (AI) have been successfully used in several fields. In this contribution I will present the idea behind the A(i)DAPT (AI for Data Analysis and Data PreservaTion) working group. Our objective is to study how AI can be used to address the main challenges in Nuclear Physics and High Energy Physics measurements: unfolding detector effects and...
The study of baryonic excited states provides fundamental information on the internal structure of the nucleon and on the degrees of freedom that are relevant for QCD at low energies. N* are composite states and are sensitive to details about how quarks are confined. Meson photo-and electro-production reactions have provided complementary information on light quark baryon spectroscopy for...
The Electron-Ion Collider (EIC) at the Brookhaven National Laboratory will allow to study the collisions of polarized electrons with polarized protons and ions. The measurement of scattered electrons and charged particles will provide the main ingredients to extract the physics information. The ePIC (electron-Proton/Ion Collider experiment) detector consists of barrel, forward, and backward...
Intense secondary beams of muons, neutrinos, and (hypothetical) dark scalar particles result from the interaction of the CEBAF 10 GeV high-current electron beam O(100 uA) and the Hall-A beam dump. While most radiation (gamma, electron/positron) is contained in the thick absorber, deep-penetrating particles (muons, neutrinos, and light-dark matter particles) propagate over a long distance,...
The ePIC detector is specifically designed to address the entire physics program at the Electron-Ion Collider (EIC). It consists of several sub-detectors, each tailored to address specific physics channels. One of the key sub-systems of ePIC is the dual-radiator Ring Imaging Cherenkov (dRICH) detector, which is a high-momentum particle-identification system located in the hadronic end-cap. For...
Silicon photomultipliers (SiPM) are selected as the photodetector technology for the dual-radiator RICH (dRICH) detector of the ePIC experiment at the future Electron-Ion Collider (EIC). A large-area prototype readout surface consisting of a total of 1280 3 x 3 mm$^{2}$ SiPM sensors was recently built and installed on the dRICH prototype during a beam test in October 2023 at the CERN-PS. The...
Silicon Photomultiplier (SiPMs) are solid-state photodetectors used for detecting light at the level of individual photons, employing avalanche multiplication as an internal gain mechanism. They have the advantage of high photon efficiency, excellent time resolution and are insensitive to the magnetic field. SiPMs are the baseline technology to equip the dual-radiator RICH detector (dRICH) of...
