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 applied Tsallis-Pareto with few parameters like the entropy
index q, the temperature T to study the transverse momentum distribution
of produced hadrons (p±, k±, p, ¯ p) in p+ p collisions at center of mass
energies psNN = 62.4,200,900 GeV and Au+Au collisions at psNN =
62.4,200 GeV at RHIC and Pb + Pb collisions at psNN =2.7TeV at
LHC.
The model parameters in addition to the average transverse momentum
of produced hadrons and flow velocity are studied as a function of collisions
energies, centralities and the mass of the produced hadrons. A
mass dependent freezout temperature is observed to exist and is the same
for particles and its antiparticle. Protons and antiprotons found smaller
values of q compared to pions and kaons.
