# Multiplicity Dependence in the Non-Extensive Hadronization Model Calculated by the HIJING++ Framework

## TL;DR

This paper explores how the parameters of the non-extensive hadronization model depend on multiplicity in high energy collisions, using the HIJING++ framework to compare with experimental data and predict high-multiplicity behavior.

## Contribution

It provides a status update on tuning the HIJING++ generator and investigates multiplicity dependence of model parameters with new calculations.

## Key findings

- HIJING++ shows good agreement with existing data
- Parameters exhibit significant multiplicity dependence
- Predictions made for high-multiplicity regions with limited data

## Abstract

The non-extensive statistical description of the identified final state particles measured in high energy collisions is well-known by its wide range of applicability. However, there are many open questions that need to be answered, including but not limited to, the question of the observed mass scaling of massive hadrons or the size and multiplicity dependence of the model parameters. This latter is especially relevant, since currently the amount of available experimental data with high multiplicity at small systems is very limited. This contribution has two main goals: On the one hand we provide a status report of the ongoing tuning of the soon-to-be-released HIJING++ Monte Carlo event generator. On the other hand, the role of multiplicity dependence of the parameters in the non-extensive hadronization model is investigated with HIJING++ calculations. We present cross-check comparisons of HIJING++ with existing experimental data to verify its validity in our range of interest as well as calculations at high-multiplicity regions where we have insufficient experimental data.
