摘要
The modification of masses as well as magnetic moments of octet baryons in the presence of hot and dense isospin symmetric strange baryonic matter has been studied using the chiral SU(3) quark mean field model. Effective masses of octet baryons are found to decrease considerably as a function of baryonic density of the nuclear medium. The strange baryons show a significant decrease in their masses in the higher baryonic density regime as compared to nucleons. Baryonic magnetic moments comprise the explicit contributions from the valence quarks, sea quarks as well as orbital angular momentum of sea quarks. The magnitudes of magnetic moments of octet baryons are found to increase as a function of the density of the nuclear medium, since the quark spin polarizations corresponding to valence quarks, sea quarks and orbital angular momentum of sea quarks vary significantly in the baryonic medium particularly in the low density and temperature region. The magnetic moments of strange baryons show a consistent behavior as a function of the strangeness fraction with the increase of the temperature of the medium, whereas in the case of nucleons the magnetic moments show an opposite behavior at T = 0 and T = 100 MeV.
