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 sNN=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. © 2020, Società Italiana di Fisica and Springer-Verlag GmbH Germany, part of Springer Nature.
