Abstract
Oscillations in modified combinants ($C_j$s) have been of interest to multiparticle production mechanisms since the 1990s. Recently, there has been a discussion on how these oscillations can be reproduced by compounding a binomial distribution with a negative binomial distribution. In this work, we explore a stochastic branching model based on a simple interaction term $\lambda\overline{\psi}\phi\psi$ 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 $p\bar{p}$ scattering that our model can reproduce.

Strengths
1. The paper is well-written
2. The proposed model is novel
3. The proposed model gives a good qualitative description of Oscillations in Modified Combinants of hadronic multiplicity distributions.
Weaknesses
1. The paper does not relate the findings of the model to state-of-the-art models for hadron production. For a full paper this may be necessary, but for a conference proceedings the current treatment is fine.
Report
This conference proceedings presents a model based on stochastic branching to explain the difference in oscillations in modified combinants of hadronic multiplicity distributions, for pp and p\bar{p} collisions respectively. By simple means, the authors demonstrate a good qualitative description of data.
For a full paper, I would have suggested the authors to at least:
(1) make a direct comparison between model/data (fig. 1 & 4) to allow more detailed comparison.
(2) compare to state-of-the-art model, such as the Herwig cluster model, which I suspect have a similar behavior, as per the authors' explanation of general features of cluster production of multiplicity. And in case it does not, such a comparison could shed light on some of the more poorly understood features of the colour structure of beam remnants (cf. the authors' sec. 4.2)
For a conference proceedings these remarks are, however, beyond the scope, and I simply leave them here for general inspiration for the authors.
