Transverse momentum spectra and suppression of charged hadrons in deformed Xe-Xe collisions at $\sqrt{s_{NN}}$ = 5.44 TeV using HYDJET++ model

Abstract

In this study, we systematically investigate deformed Xe-Xe collisions at 5.44 TeV center of mass energy. We exploit Monte Carlo HYDJET++ model to compute transverse momentum (pT ) distribution, nuclear modification factor RAA and relative suppression in terms of RCP as a function of transverse momentum and centrality of collision of charged hadrons in body-body and tip-tip geometrical configurations, respectively. We have compared HYDJET++ model results to those from ALICE experimental data and AMPT model (String-Melting version) results. Minimum bias Xe-Xe collisions show a suitable match with ALICE experimental data at midrapidity. Average transverse momentum ( pT ) show strong centrality dependence. The contribution of hard parton scatterings to the total charged hadron yield is discussed. Both nuclear modification factor RAA and relative suppression RCP show clear dependence on centrality as well as transverse momentum. The charged hadron observables show clear dependence on the geometrical configuration of the collisions. HYDJET++ model justifies experimental data more closely than AMPT model.
