“…Many studies are available in the literature adopting different strategies, for example, chiral quark model, QCD sum rules, light cone QCD models etc., to calculate the electromagnetic properties such as magnetic moments and electromagnetic form factors of baryons in the free space [1][2][3][4][5][6][7][8][9][10]. Exploring the impact of finite density of nuclear matter under strong interactions on the electromagnetic properties has also got attention.…”

In the present work we study the masses and magnetic moments of decuplet baryons in isospin asymmetric strange hadronic medium at finite temperature using chiral SU(3) quark mean field model. In the strange isospin asymmetric medium, the properties of baryons in chiral SU(3) mean field model are modified through the exchange of scalar fields σ, ζ and δ and the vector fields ω, ρ and φ. The scalar-isovector field δ and the vector-isovector field ρ signifies the finite isospin asymmetry of the medium. We calculate the in-medium constituent quark masses and masses of decuplet baryons in asymmetric strange matter within the chiral SU(3) quark mean field model and use these as input in the constituent chiral quark model to calculate the in-medium magnetic moments of decuplet baryons for different values of isospin asymmetry and strangeness fraction of hot and dense medium. For calculating the magnetic moments of baryons, contributions of valence quarks, quark sea and orbital angular momentum of quark sea are considered in the calculations.

“…The magnetic moment of the particle plays an important role in the study of structure of matter at the subnuclear level, as it largely depends upon its structure and structure parameters. Theoretically, the magnetic moments of octet as well as decuplet baryons have been ex-tensively studied in free space [7][8][9][10][11][12][13]. Constituent quark model studies proposed that the baryonic magnetic moments can be calculated by summing the magnetic moments of constituent quarks [14,15].…”

We have calculated the in-medium magnetic moments of octet baryons in the presence of hot and dense symmetric nuclear matter. Effective magnetic moments of baryons have been derived from medium modified quark masses within chiral SU(3) quark mean field model. Further, for better insight of medium modification of baryonic magnetic moments, we have considered the explicit contributions from the valence quarks, sea quarks as well as sea orbital angular momentum of sea quarks. These effects have been successful in giving the description of baryonic magnetic moments in vacuum. The magnetic moments of baryons are found to vary significantly as a function of density of nuclear medium. * Electronic address:
