Predictions for Transverse Momentum Spectra and Elliptic Flow of Identified Particles in Xe+Xe Collisions at $$\sqrt{s_\mathrm{NN}}$$ = 5.44 TeV Using a Multi-phase Transport Model (AMPT)

Abstract

Relativistic collisions of Xe\(+\)Xe at Large Hadron Collider give us an opportunity to study the properties of possible state of deconfined quarks and gluons, where the size of the produced system lies between the p\(+\)p and Pb\(+\)Pb collisions. In the present study, we have incorporated nuclear deformation in a multi-phase transport (AMPT) model to study the identified particle production and elliptic flow in Xe\(+\)Xe at \(\sqrt{s_\mathrm{NN}} = 5.44\) TeV. In more comprehensive way, we have studied \(p_\mathrm{T}\)-differential and \(p_\mathrm{T}\)-integrated particle ratios to pions and kaons as a function of centrality and the number of constituent quark (\(n_q\)) and transverse mass (\(m_\mathrm{T}\)) scaling of elliptic flow. The effect of deformation on particle production has also been highlighted by comparing with non-deformation case. The \(p_\mathrm{T}\)-differential particle ratios show a strong dependence on centrality whereas \(p_\mathrm{T}\)-integrated ratios are almost independent of centrality.
