/ Abstract
Abstract.The energy dependence of Tsallis statistics parameters is presented for charged pions produced at beam energies ranging between 6.3GeV and 7TeV. It is found that deviations from Boltzmann statistics are monotonically growing with beam energy. The energy dependence of the parameters T and q of the negatively charged pions in the energy range $ 6.3 < \sqrt{s} < 7000$6.3<s<7000 GeV reveals that the deviation of the transverse momentum distribution from the exponential becomes more and more pronounced as the beam energy is increased. The parameter q increases with beam energy while the temperature T slowly decreases.
