Abstract in Portuguese
Neste trabalho foram estudados modelos termodinâmicos baseados na estatística não extensiva de Tsallis através da análise de dados de distribuições de momento transversal de colisões do tipo próton-próton em energias ultra relativísticas. Os resultados dessa análise confirmam um comportamento constante do índice entrópico bem próximo do valor teórico preestabelecido de q=8/7 para sistemas termodinâmicos que se comportam como termofractais.

Abstract in English
In this work, thermodynamic models based on the non-extensive statistics of Tsallis were studied through the analysis of data from transverse momentum distributions of proton-proton collisions at ultra-relativistic energies. The results of this analysis confirm a constant behavior of the entropic index very close to the pre-established theoretical value of q=8/7 for thermodynamic systems that behave as thermofractals.
