Abstract
Using the unification of the chiral SU(3) model and QCD sum rules, we deduce the in-medium properties of $K^\pm_1$ meson. Within the chiral SU(3) model, medium modified gluon and quark condensates are evaluated through their interactions with the scalar fields ($\sigma$, $\zeta$, $\delta$, and $\chi$). These condensates are further used as input in the Borel transformed equations of QCD sum rules to evaluate the in-medium mass of strange $K^\pm_1$ meson. The in-medium property of the above meson can be used to study the restoration of chiral symmetry in nuclear matter.

Report
In-medium properties of K1± meson is deduced using unification of the chiral SU(3) model and QCD sum rules. It has been found that the charge symmetry does not hold in the nuclear medium for K1 meson as the medium influenced mass of K1−(u ̄s) meson modifies significantly at nuclear saturation density whereas in-medium mass K1+(us ̄) meson modifies less. It is well written and I recommend ir for publicaiton.
