Particle production at large $p_T$ in Xe+Xe collisions with jet quenching using the higher twist approach

Abstract

The production of ${\pi }^0$, $\eta$, and $\varphi$ in the most central (0%-5%) Xe+Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV is investigated in the framework of the perturbative QCD (pQCD) improved parton model at an accuracy of next-to-leading order (NLO). The jet quenching effect is effectively incorporated by medium-modified fragmentation functions via the higher-twist approach. Predictions of the nuclear modification factors of ${\pi }^0$, $\eta$, and $\varphi$ as functions of the transverse momentum $p_{\mathrm{T}}$ are made with the jet transport parameter ${\hat{q}}_0$, which is extracted from the available experimental data of charged hadrons provided by ALICE and CMS. The particle ratios $\eta /{\pi }^0,\varphi /{\pi }^0$ as functions of $p_{\mathrm{T}}$ in Xe+Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV as well as in 0%-5% Pb+Pb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV are also presented. The numerical simulations of the scaled ratios of charged hadron production in the Xe+Xe 5.44 TeV system over those in the Pb+Pb 5.02 TeV system give a good description of the CMS data, and the scaled ratios of ${\pi }^0$, $\eta$, and $\varphi$ production coincide with the curve of charged hadron production.
