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 √<span style="margin-left:-2px;margin-right:2px;margin-top:2px; border-top:1px solid black">s _NN</span> =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.
