Description
Identified hadron spectra from recent years are analyzed in the non-
extensive thermodynamical framework. The Tsallis-Pareto cut power-law
is known to describe the pT distributions for a wide energy range, but
its origin is thermodynamical-model dependent [1,2].
We pursue the physical origin of this observation by investigating the
center-of-mass energy, multiplicity, mass and strangeness dependency of
the Tsallis q and T parameters comprehensively from ee, pp to pA
collisions [3,4]. We describe the main characteristics of a statistical
hadronization model that could explain our observations. We present the
Tsallis-thermometer, which can be use to gain more information on the
high-energy nuclear collisions even for the smallest system [5].
