Description
Transverse spherocity is an event-shape observable that quantifies the azimuthal distribution of transverse momentum, enabling a clean separation between jetty-like (low spherocity) and isotropic (high spherocity) final states. By using event topology with spherocity, one can disentangle soft, collective-dominated particle production from hard, jet-driven processes without relying solely on multiplicity. Spherocity differential study of charged-particle production in Pb–Pb collisions at $\sqrt{{s}_{NN}}$ = 5.02 TeV using events from EPOS4 model are presented. Charged-particle pseudorapidity densities versus centrality are evaluated. Identified hadron spectra ($\pi^{\pm}$, $K^{\pm}$, $p (\overline{p})$) at mid-rapidity (|η| < 0.8) are measured for jetty and isotropic classes across centrality intervals, and “crossing points” in transverse momentum are mapped as a function of centrality and particle species.
