Charged particle production as a function of multiplicity and spherocity in pp, p-Pb and Pb-Pb collisions at $\sqrt{s_{\rm NN}}$=5.02 TeV

This work presents the results that was obtained during the CERN Summer Student Programme 2021. In order to investigate the event structure of collisions, we conducted an analysis of pp, p-Pb and Pb-Pb collisions with collision energy $\sqrt{s_{\rm NN}} = 5.02$ TeV covering the kinematic range $|\eta| < 0.8$ and $p_{\rm T} \geq 0.15$ GeV/$c$, $ 0.15 < p_{\rm T} \leq 4$ GeV/$c$ and $ 4 < p_{\rm T} \leq 20$ GeV/$c$. Spherocity distributions and ratios were obtained for all three types of collisions, considering low, middle and high multiplicity classes. Transverse momentum spectra were investigated for the collisions. The measurement of average transverse momentum of particles as a function of event multiplicity was analyzed taking into account spherocity to characterize the event structure.
