From tsallis scheme of high-energy pp collisions to generalized multiplicity distribution with modified combinants

Abstract

An analysis of the generalized multiplicity distribution, (GMD), has been made in high energy pp collisions. An attempt is made to reconcile the generating function of GMD with Tsallis statistics in order to find an interpretation of Tsallis parameter, (q). The modified combinants, (Cj’s), for both GMD and NBD are obtained using the generating functions of these distributions. Our results show that single NBD does not lead to the oscillatory behaviour of the observed Cj. However, for GMD the corresponding Cj not only oscillate but also show the fading-down feature of the experimentally observed Cj. This could help in future to analyse the physical process which is responsible for these oscillations. © The Authors, published by EDP Sciences.
