Abstract: We show that the inclusion of long distance effect, expected in strong interactions, through a nonextensive thermodynamical approach is able to explain the experimental distribution of the transverse momentum of the hadrons with respect to the jet axis (pt)e+e−→hadron reaction. The observed deviation from the exponential behavior, predicted by the Boltzmann–Gibbs thermodynamical treatment, is automatically recovered by the nonextensive Tsallis statistics used here. We fitted the observed pt spectrum in the range of 14–161 GeV and obtained, besides a good fit, the theoretically important fact that the temperature becomes independent of the primary energy.
