Abstract

Recently, CERN Large Hadron Collider has performed a collision experiment of xenon–xenon (Xe–Xe) nuclei at $\sqrt{s_{NN}} = 5.44\hbox {TeV}$ . 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 ( $(\hbox {d}n_{\hbox {ch}}/\hbox {d}\eta )_{\eta =0}$ ) 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 $(\hbox {d}n_{\hbox {ch}}/\hbox {d}\eta )_{\eta =0}$ with respect to the number of participating quarks, $N_{q}$ . We observed that Class II results satisfy the experimental data quite well.
