The effect of Kaon Condensation on Quark-Antiquark Condensate in Dense Matter

Abstract

Assuming that at sufficiently high densities the constituent quarks become relevant degrees of freedom, we study within the framework of a chiral quark model the influence of s-wave $K^{-}$ condensation on the quark-antiquark condensates. We find that, in linear density approximation, the presence of a $K^{-}$ condensate quenches the $\bar{u}u$ condensate, but that the $\bar{d}d$ condensate remains unaffected up to the chiral order under consideration. We discuss the implication of the suppressed $\bar{u}u$ condensate for flavor-dependent chiral symmetry restoration in dense matter
