Octet Baryon Masses and Magnetic Moments in Hot and Dense Isospin Asymmetric Nuclear Matter

TL;DR

This study investigates how the magnetic moments of octet baryons change in hot, dense, isospin asymmetric nuclear matter using a chiral SU(3) quark mean field model, revealing significant medium and temperature effects.

Contribution

It introduces a medium modified quark and baryon mass model to analyze baryon magnetic moments in asymmetric nuclear matter at finite temperature.

Findings

Magnetic moments vary significantly with density and isospin asymmetry.

Temperature increase reduces the effects of isospin asymmetry.

Results may help interpret experimental measurements of baryon magnetic moments.

Abstract

Medium modification of the magnetic moments of octet baryons in the isospin asymmetric nuclear medium at finite temperature has been calculated using medium modified quark and baryon masses derived in chiral SU(3) quark mean field model. The magnetic moments of baryons are found to vary significantly as a function of density of nuclear medium as well as with the increase in isospin asymmetry of the medium. The rise of temperature is found to decrease the effect of isospin asymmetry on masses and magnetic moments of baryons. The results of present investigation may be helpful to understand the experimentally observed values of octet baryon magnetic moments at different experimental facilities.
