Oscillations in Modified Combinants of Hadronic Multiplicity Distributions

Abstract

Oscillations in modified combinants (C_jCjs) 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 \lambda\overline{\psi}\phi\psiλψ¯ϕψ 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_jCjs and explore its physical implications. We find that there is a significant difference in the oscillations in C_jCjs between high energy pp and p\bar{p}pp‾ scattering that our model can reproduce.
