Pion, Kaon and Antiproton Production in Pb+Pb Collisions at LHC Energy √s NN=2.76 TeV: A Model-Based Analysis

Abstract

Large Hadron Collider (LHC) had produced a vast amount of high precision data for high energy heavy ion collision. We attempt here to study i) transverse momenta spectra, ii) K/π, P/π ratio behaviours, iii) rapidity distribution, and iv) the nuclear modification factors of the pion, kaon and antiproton produced in P+P and Pb+Pb collisions at energy s NN=2.76 TeV, on the basis of Sequential Chain Model (SCM). Comparisons of the model-based results with the measured data on these observables are generally found to be modestly satisfactory.
