Multiparticle production processes from the nonextensive point of view

Abstract

We look at multiparticle production processes from the nonextensive point of view. Nonextensivity means here the systematic deviations in exponential formulas provided by the usual statistical approach for description of some observables like transverse momenta or rapidity distributions. We show that they can be accounted for by means of single parameter q with |q-1| being the measure of nonextensivity. The whole discussion will be based on the information theoretical approach to multiparticle processes proposed by us some time ago.
