摘要

This study investigates the medium modifications of the magnetic moments and transition properties of low-lying spin-parity \(J^P = 1/2^-{ and}3/2^- \varLambda { resonances},\,{ suchas}\varLambda (1405){ with}1/2^-{ and}\varLambda (1520){ with}3/2^-,\,{ inhotanddensehadronicmatterusingthechiralSU}(3){ quarkmeanfieldmodel}.{ Inthismodel},\,{ quarksconfinedinsidethebaryonsaremodifiedthroughtheexchangeofscalarfields} \sigma ,\, \zeta ,\,{ and} \delta { andvectorfields} \omega ,\, \rho ,\,{ and} \phi \) 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 \(\varLambda \) resonances in high density environments.
