Non-extensive Boltzmann Equation and Hadronization

Abstract

For a general, associative addition rule defining a non-extensive thermodynamics we construct the strict monotonic function, which transforms it to an additive quantity. We investigate the evolution of one-particle distributions in the framework of a two-body Boltzmann equation supported with a non-extensive energy addition rule. In particular we study the emergence of a Tsallis distribution as a stationary solution. We propose that for describing the hadronization of quark matter non-extensive rules may apply.
