Abstract: (Springer)
The in-medium properties of η\eta mesons are studied in hot and dense isospin asymmetric strange magnetized matter using the chiral SU(3) hadronic mean-field model. The scalar and vector density of baryons are expressed in terms of thermal distribution functions at finite temperature and magnetic field and have a dependence on the scalar fields σ\sigma , ζ\zeta , and δ\delta through the effective mass of baryons and the dependence on the vector fields ω,ρ\omega , \rho , and ϕ\phi through the effective chemical potential. The properties of η\eta mesons get modified in a hot and dense magnetized environment through the medium-modified nucleons and hyperons. The negative mass shift obtained gives rise to optical potential, which is attractive in the medium and suggests a possibility of η\eta -mesic bound states formation. The addition of hyperons in the medium enhances the attractive interactions and causes an increased negative mass shift for η\eta mesons.
