Abstract

Non extensive statistics provide an excellent application in the field of high energy collisions to study the thermal properties of the produced particles. We apply the scaled Tsallis equation to study the entropy parameter as a function of transverse momentum of the produced hadrons. We applied Tsallis-Pareto to study the transverse momentum distribution of produced hadrons ( ,  ,  ,  ) in pp collisions at center of mass energies  = 62.4 , 200 ,900 GeV and 2.7 TeV . The Pareto-Tsallisdistribution, leads to an excellent description of data on transverse momentum distribution .The parameters are almost independent from  for protons and kaons and distributed around  and q is increasing for pions from 1.1 to almost 1.3 at top energy . The effective temperature,  increases with collisions energy we estimated  for pp collisions at 2.7 TeV LHC energy. Different hadrons have different effective temperature such that heavier hadrons have higher freezout temperature.
