Abstract.

An approach, based on Tsallis non-extensive statistics, has been employed, here, to analyse, systematically, the p T -spectra of various identified secondary hadrons like pions, kaons, protons and antiprotons, produced in different central Pb + Pb interactions at LHC energy 2.76TeV in terms of multiplicity and temperature fluctuations. The results, thus obtained, have been utilized to understand the various stages of different types of hadron production during evolution of the fireball produced in such collisions.
