Description
In this study, we have calculated the transition magnetic moments of the decuplet $\left(J^p = \frac{3}{2}^+\right)$ to octet $\left(J^p = \frac{1}{2}^+\right)$ baryon transitions as a function of density for symmetric nuclear matter at different values of the temperature. The impact of the density and temperature has been realized through the chiral SU(3) mean field model ($\chi CQMF$) which considers quarks as the fundamental degrees of freedom. Within the framework of $\chi CQMF$, the impact on the properties of baryons (including mass) is defined through effective masses and energies of the constituent quarks which are modified through the exchange of exchange of scalar and vector fields. The impact thus calculated is then used as an input in this first study on the calculation of effective transition magnetic moments for decuplet to octet transitions using constituent chiral quark model ($\chi CQM$). The explicit effective contributions coming from valence quarks, sea quark and orbital angular momentum of quark sea have been included in total value of effective transition magnetic moments. The values of the effective transition magnetic moments have also been compared with available experimental results and other theoretical studies as well. Magnetic moments of the baryons serve as an important candle in scrutinizing the structure and the properties of light baryons.
