Description
This study investigates the medium modifications of the magnetic moments and transition properties of low-lying spin-parity $J^P = 1/2^-$ and $3/2^-$ $\Lambda$ resonances, such as $\Lambda(1405)$ with $1/2^-$ and $\Lambda(1520)$ with $3/2^-$, in hot and dense hadronic matter using the chiral SU(3) quark mean field model. In this model, quarks confined inside the baryons are modified
through the exchange of scalar fields $\sigma$, $\zeta$, and $\delta$ and vector fields $\omega$, $\rho$, and $\phi$ which results in shift in quark masses and interaction energies. By analyzing these field-induced modifications, the model enables us to calculate the effective masses and magnetic moments of the quarks and to estimate the impact on the magnetic moments and transition properties of $\Lambda$ resonances in high density environments.
