Exploring the effect of hadron cascade-time on particle production in Xe+Xe collisions at $\sqrt{s_{\rm{NN}}}$ = 5.44 TeV through a multi-phase transport model

Abstract

Heavy-ion collisions at ultra-relativistic energies provide extreme conditions of energy density and temperature to produce a deconfined state of quarks and gluons. Xenon (Xe) being a deformed nucleus further gives access to the effect of initial geometry on final state particle production. This study focuses on the effect of nuclear deformation and hadron cascade-time on the particle production and elliptic flow using A Multi-Phase Transport (AMPT) model in Xe+Xe collisions at √ sNN = 5.44 TeV. We explore the effect of hadronic cascade-time on identified particle production through the study of pT-differential particle ratios. The effect of hadronic cascade-time on the generation of elliptic flow is studied by varying the cascade-time between 5 and 25 fm/c. This study shows the final state interactions among particles generate additional anisotropic flow with increasing hadron cascade-time especially at very low and high-pT.
