Description
The impact of density and temperature on pseudoscalar $D_s$ and $B_s$ mesons is analyzed within an isospin-asymmetric resonance matter using the chiral SU(3) model combined with a QCD sum-rule approach. The quark and gluon condensates obtained from the chiral SU(3) model serve as input to the QCD sum rule approach, enabling the calculation of in-medium masses of $D_s$ and $B_s$ mesons. These effective masses are markedly altered by the presence of $\Delta$-resonance baryons in the medium, highlighting the strong sensitivity of $u$, $d$ and $s$ light quarks in mesons to the surrounding hot and dense hadronic environment. Therefore, a clear understanding of these effects is crucial for the precise interpretation of quark–gluon plasma signatures and can improve the analysis of future heavy-ion collision data from FAIR experiments such as CBM and PANDA.
