Predictions for Transverse Momentum Spectra and Elliptic Flow of Identified Particles in Xe+Xe Collisions at √sNN = 5.44 TeV Using a Multi-phase Transport Model (AMPT)

Abstract

Relativistic collisions of Xe + Xe at Large Hadron Collider give us an opportunity to study the properties of possible state of deconfined quarks and gluons, where the size of the produced system lies between the p + p and Pb + Pb collisions. In the present study, we have incorporated nuclear deformation in a multi-phase transport (AMPT) model to study the identified particle production and elliptic flow in Xe + Xe at sNN=5.44 TeV. In more comprehensive way, we have studied pT -differential and pT -integrated particle ratios to pions and kaons as a function of centrality and the number of constituent quark (nq ) and transverse mass (mT ) scaling of elliptic flow. The effect of deformation on particle production has also been highlighted by comparing with non-deformation case. The pT -differential particle ratios show a strong dependence on centrality whereas pT -integrated ratios are almost independent of centrality. © 2021, Springer Nature Singapore Pte Ltd.
