Abstract

The objective of this work is to measure the multiplicity distribution of p-p collisions at 5.36 TeV using the data of the Alice experiment. These collisions will be generated at Large Hadron Collider (LHC) in 2024 for the first time. In addition, a systematic study of multiplicity distributions of different collisions (proton-proton and proton-Pb) will be carried out in the various energies already measured in the LHC (0.9, 7 and 8 TeV for proton-proton collisions and 5.02 TeV for proton-proton collisions Pb). We will seek to obtain a clearer description of the competition between particle production mechanisms in hadronic collisions as a function of energy, from the verification of various models and scaling properties of multiplicity distributions.
