Modifications on nucleon parameters at finite temperature

TL;DR

This paper investigates how the mass and residue of the nucleon change with temperature using thermal QCD sum rules, revealing stability at low temperatures and decline at higher temperatures.

Contribution

It introduces modifications to nucleon parameters at finite temperature by incorporating additional operators in thermal QCD sum rules.

Findings

Nucleon mass and residue are stable at low temperatures.

They decrease after reaching a certain temperature.

The study provides insights into nucleon behavior in hot environments.

Abstract

Taking into account the additional operators coming up at finite temperature, we investigate the mass and residue of the nucleon in the framework of thermal QCD sum rules. We observe that the mass and residue of the nucleon are initially insusceptible to increase of temperature, however after a certain temperature, they start to fall increasing the temperature.
