$D$ and $D^*$ mesons in isospin asymmetric nuclear medium
We investigate the properties of pseudoscalar $D$ and vector $D^*$ mesons in an isospin asymmetric nuclear medium using a hybrid approach that integrates the light-front quark model with the chiral SU(3) quark mean field model. The influence of isospin asymmetric nuclear medium is examined by utilizing the in-medium quark masses derived from the chiral SU(3) quark mean field model as an input in the light-front quark model to study the medium modification of $D$ mesons. We examine the impact of isospin asymmetry and baryon density at zero and finite temperature on the effective masses, weak decay constants, and distribution amplitudes of the pseudoscalar mesons $D^0$, $D^+$, $D_s$, and the vector mesons $D^{0*}$, $D^{+*}$, and $D_s^*$. Our results indicate significant medium-induced changes for pseudoscalar $D$ and vector $D^*$ mesons having $u/d$ as one of their constituent quarks, while a comparatively reduced effect is observed for mesons containing a strange quark. In contrast to temperature and isospin asymmetry, changes in the baryon density of the nuclear medium have a larger effect on different properties of $D$ and $D^*$ mesons.
