Parton Branching in Color Mutation Model

TL;DR

This paper improves the eikonal color mutation branching model for soft hadronic collisions by refining the initial parton distribution and demonstrating that key moments and their energy dependence can be accurately modeled with just two parameters.

Contribution

It introduces an improved treatment of the initial parton distribution and incorporates Furry branching to better describe nonperturbative soft interactions.

Findings

All moments <n> and C_q for q=2,...,5 are correctly determined.

Energy dependence of moments is accurately modeled.

Model uses only two parameters to fit the data.

Abstract

The soft production problem in hadronic collisions as described in the eikonal color mutation branching model is improved in the way that the initial parton distribution is treated. Furry branching of the partons is considered as a means of describing the nonperturbative process of parton reproduction in soft interaction. The values of all the moments, <n> and $C_q$, for q=2,...,5, as well as their energy dependences can be correctly determined by the use of only two parameters.
