Oscillations in Modified Combinants of Hadronic Multiplicity Distributions

Abstract

Oscillations in modified combinants (C j s) have been of interest to multiparticle production mechanisms since the 1990s [1]. Recently, there has been a discussion on how these oscillations can be reproduced by compounding a binomial distribution with a negative binomial distribution [2, 3]. In this work, we explore a stochastic branching model based on a simple interaction term λψφψ for partons and propose a hadronization scheme to arrive at the final multiplicity distribution.We study the effects that compounding our model with a binomial distribution has on C j s and explore its physical implications. We find that there is a significant difference in the oscillations in C j s between high energy pp and pp scattering that our model can reproduce.
