Description

We present the in-medium mass modification of $D$ ($D^+$, $D^0$) and $\bar D$ ($D^-$, $\bar {D^0}$) mesons when immersed in isospin asymmetric $\Delta$ resonance matter by using the chiral SU(3) hadronic model extended to the SU(4) sector.
The interactions of $D$ and $\bar D$ mesons with decuplet baryons ($\Delta^{++,+,0,-}$) are explicitly taken into account in the dispersion relations in addition to nucleons. The properties of $D$ ($\bar D$) mesons are modified at finite density and temperature of asymmetric resonance matter through the exchange of scalar fields $\sigma, \zeta$ and $\delta$ and the vector fields $\omega$ and $\rho$.
At finite temperatures, the effective masses of $D$ ($\bar D$) mesons undergo substantial modifications due to the presence of $\Delta$ resonance baryons within the medium. The significance of isospin-dependent medium effects is especially important for future asymmetric HIC studies.
