Exploring the effect of hadron cascade time on particle production in Xe+Xe collisions at sNN =5.44 TeV using a multiphase transport model

Abstract

Heavy-ion collisions at ultrarelativistic 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 multiphase transport (AMPT) model in Xe+Xe collisions at sNN=5.44TeV. 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 25fm/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. © 2022 authors.
