How low is the thermodynamical limit?

Abstract

We analyze how can some dynamical process lead to (almost) exponential distribution of hadrons without instantaneous equipartition with a heat bath. We present a model for parton dressing whic re-combines the exponential from cut power law minijet distributions as a limiting distribution. Thermal models and power law tails are interpreted within the framework of the more general Tsallis distribution.
