Open strange meson $K^\pm_1$ in hot and dense nuclear matter

Abstract

Using the unification of the chiral SU(3) model and QCD sum rules, we deduce the in-medium properties of K^\pm_1K1± meson. Within the chiral SU(3) model, medium modified gluon and quark condensates are evaluated through their interactions with the scalar fields (\sigmaσ, \zetaζ, \deltaδ, and \chiχ). 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_1K1± meson. The in-medium property of the above meson can be used to study the restoration of chiral symmetry in nuclear matter.
