Thermal Models for Hadron Production in Relativistic Heavy-Ion Collisions

Abstract

In this work, we investigate hadron production in relativistic proton–lead and protonproton collisions using phenomenological thermal-statistical models. The transverse momentum spectra (pT ) of identified pions, kaons and protons are analyzed with the Blast-Wave Model framework. The theoretical results show good agreement with experimental measurements from the ALICE Collaboration at CERN, successfully reproducing the spectra of different particle species and collision centralities. In addition, an improved Blast-Wave model is implemented in Monte Carlo simulations, which allows for hadron 3-momenta generation within the experimental acceptance, for its use in phenomenological applications. After validation, we finally apply the Monte Carlo code to generate pair distribution of hadrons as a function of their relative momentum
