An analysis involving the light front variables is performed over the\ninclusively produced \π\±, K\± and p(\p) in the Pb-Pb\ncollisions simulated using the UrQMD event generator at \√(s) = 2.76 TeV\nto study the possible formation of a thermalised medium in these collisions. It\nis demonstrated that there exist surfaces defined by constant values of the\nlight front variable in the phase space of these hadrons which can select a\ngroup of thermalised particles. The temperatures are extracted for each species\nand are compared with those obtained from a similar calculation involving the\nkinematical and acceptance restrictions which are typically bound to the\ncollider experiments. It is shown that the analysis is feasible to perform with\nthe data collected at the ALICE experiment at LHC. The analysis may be\nconsidered as a prototypical study to a similar experimental analysis of the\ndata from the heavy-ion collisions at RHIC and LHC after implementing the\nnecessary corrections and calibrations relevant to the experimental\napparatuses.\n
