Abstract

In this work, we study the applicability of the concepts of self-consistency by R. Hagedorn and non-exntensivity according to the Tsallis statistic. These two concepts can be associeted in accordance with the self-consistency non-extensive theory. The analysis of distribution data of transverse momentum and mass spectrum allows hadron test applicability of these concepts, and in this work we developed this analysis for data obtained from pp collisions at ultrarelativistic energies. The results of these analysis support the ideia of the existence of a Hagedorns temperature threshold for hadronic systems and a very good description of the hadroic mass spectrum by the self-consistency non-extensive theory is also verified. Part of this work is published in Physical Review D 87, 114022 (2013). (AU)
