Multiparticle production and geometric scaling in 5.44 TeV Xe–Xe collisions at the CERN large hadron collider using wounded quark model

Abstract

Recently, CERN Large Hadron Collider has performed a collision experiment of xenon–xenon (Xe–Xe) nuclei at √sN N = 5.44TeV. The experiment based on Xe–Xe nuclei can provide a deeper understanding of the particle production mechanism in QCD. In this article, we have studied midrapidity pseudorapidity density ((dnch/dη)η=0) of charged hadrons with respect to collision centrality using the modified version of wounded quark model (WQM). In WQM, we have constructed minimum-bias event sets in two different ways denoted as Class I and Class II. Further, we have shown the scaling behavior of(dnch/dη)η=0 with respect to the number of participating quarks, Nq . We observed that Class II results satisfy the experimental data quite well.
