The present paper is a comparative study of transverse momentum spectra of − mesons, hyperons, multi-strange baryons , and in the most central Pb–Pb collisions at = 2.76 and 5.02 TeV for the mid rapidity interval < 0.5 by using two different Monte Carlo simulation models, EPOS-1.99 and EPOS-LHC. Particle ratios are studied at the two center-of-mass energies to understand the enhancement of heavier hadrons over the lighter ones. Nuclear modification factors are also constructed for multi-strange baryons at = 2.76 TeV to study particle production and energy loss mechanisms. The validity of these models is tested for Pb–Pb collisions at = 2.76 and 5.02 TeV by comparing the simulation data with ALICE experimental data.
