Predictions for azimuthal anisotropy in Xe+Xe collisions at sNN =5.44 TeV using a multiphase transport model

Abstract

Xe+Xe collision at relativistic energies may provide us with a partonic system whose size is approximately in between those produced by p+p and Pb+Pb collisions. The experimental results on anisotropic flow in Xe+Xe and Pb+Pb collisions should provide us with an opportunity to study the system size dependence of v2. In the present work, we have used a multiphase transport model to calculate charged particles' v2 for Xe+Xe collisions at sNN=5.44TeV. We have also tried to demonstrate the number of constituent quark, Nq, and mT scaling of the elliptic flow. We find that nq scaling of v2 is not observed for the identified hadrons. The v2 results from Xe+Xe collisions have also been compared to Pb+Pb collisions at sNN=5.02TeV. We find that flow of charged particles in (50-60)% central collisions for xenon nuclei is almost 30% less than particle flow developed in lead ion collisions, implying the important role the system size plays in the development of particle collective motion in relativistic heavy ion collisions. © 2018 authors.
