$pT$ spectra and multiplicity vs centrality in $Pb-Pb$ collisions at $√sNN = 5.02 TeV$

This document summarizes the work done in the Summer Program 2021. We studied Pb-Pb collisions at {sqrt{s_{NN}}= 5.02} TeV. First, the multiplicity vs centrality spectrums are considered, to separate the low and high multiplicity parts of each centrality class. Then, several {p_T} ratios are studied, discussing its implications.
