Abstract

We investigate the in-medium masses and magnetic moments of decuplet baryons (Δ,Σ*,Ξ*,Ω−) in isospin asymmetric magnetized strange matter at finite temperature within a unified chiral effective framework. Medium modifications of baryons are implemented using the chiral SU(3) quark mean-field (CQMF) model, where constituent quarks interact via scalar (σ,ζ,δ) and vector (ω,ρ,ϕ) meson fields considering the Dirac sea effects. The external magnetic field is incorporated through Landau quantization of charged particles together with anomalous magnetic moments of baryons. The resulting in-medium mass of constituent quarks and decuplet baryons obtained from the CQMF model are subsequently employed as inputs to the chiral constituent quark model (χCQM) to evaluate magnetic moments of baryons. Our results provide a systematic understanding of how dense, hot, and magnetized environments influence the magnetic properties of decuplet baryons.
