Finite Size Corrected Relativistic Mean-Field Model and QCD Critical End Point

TL;DR

This paper investigates how finite hadron size influences the QCD phase diagram, showing that baryon size shifts the critical end point to higher chemical potentials using a combined relativistic mean field and Bag model approach.

Contribution

It introduces finite size corrections into the QCD phase diagram analysis within a relativistic mean field and Bag model framework, providing new insights into the CEP location.

Findings

Finite hadron size shifts the CEP to higher chemical potentials.

Finite size effects modify the equation of state for the hadronic phase.

The model maintains thermodynamic consistency with Van der Waals interactions.

Abstract

The effect of finite size of hadrons on the QCD phase diagram is analyzed using relativistic mean field model for the hadronic phase and the Bag model for the QGP phase. The corrections to the EOS for hadronic phase are incorporated in a thermodynamic consistent manner for Van der Waals like interaction. It is found that the effect of finite size of baryons is to shift CEP to higher chemical potential values.
