Thermodynamical Consistency of Excluded Volume Hadron Gas Models

TL;DR

This paper critically examines a recent excluded volume hadron gas model, revealing that it fails to satisfy thermodynamical consistency due to discrepancies between different calculation methods.

Contribution

The paper identifies and discusses the thermodynamical inconsistency in the Singh et al. hadron gas model, highlighting the need for model revisions.

Findings

Discrepancies between thermodynamical relations and statistical ensemble results

The model does not satisfy thermodynamical consistency requirements

Highlights the importance of thermodynamical consistency in hadron gas models

Abstract

The new excluded volume hadron gas model by Singh et al. [1-7] is critically discussed. We demonstrate that in this model the results obtained from relations between thermodynamical quantities disagree with the corresponding results obtained by statistical ensemble averaging. Thus, the model does not satisfy the requirements of thermodynamical consistency.
