Magnetic Moments of ½– Baryon Resonances in Strange Hadronic Matter at High Densities

Year: 2025

Type: article

Abstract: This work primarily focuses on determining the magnetic moments of $\frac{1}{2}^-$ baryon resonances in the presence of hot and dense hadronic matter. In the chiral $SU(3)$ quark mean field model approach, we have essentially accounted for the effects on in-medium scalar meson fields to investigate the impact of high densities on the in-medium baryon masses and their constituent quarks. In light of the chiral constituent quark model $\chi$CQM, we have calculated the magnetic moments of $\frac{1}{2}^-$ baryon resonances and scrutinized the effects due to its internal constituents: the valence quarks, sea quarks, and the orbital moment of sea quarks. Furthermore, we have investigated the effective baryonic magnetic moments for the finite magnitudes of isospin asymmetry and strangeness fraction.
