Bose-Einstein correlations in cascade processes and non-extensive statistics

Abstract

We discuss the effect of nonextensivity of the emitting source on the Bose-Einstein correlations (BEC). This is done numerically by comparing cascade hadronization model (CAS), which is known to exhibit fractal structure in both space-time and phase-space, with its equivalent obtained from the information theory approach (MaxEnt), in which hadronization proceeds uniformly in the phase-space. To this end we have developed a new method of accounting for BEC in Monte Carlo event generators, which preserves all kinematics of the hadronization process.
