Contribution

It introduces a detailed theoretical framework for hadron yield correlations in combination models, including effects of net quark excess and decay contributions.

Findings

Derived relationships between hadron yields in equal quark-antiquark systems

Analyzed the impact of net quark excess on hadron production

Compared model predictions with experimental data

Abstract

We study the hadron yield correlation in the combination models in high energy heavy ion collisions. We derive the relationship between the average yields of different hadrons produced in the combination of a system consisting of equal number of quarks and antiquarks. We present the results for the directly produced hadrons as well as those for the final hadrons including the strong and electromagnetic decay contributions. We also study the net quark influence by considering the case when the number of quarks is larger than that of the antiquarks. We make comparison with the data wherever possible.
