The effect of kaon condensation on quark–antiquark condensate in dense matter Original Research Article

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 View the MathML source condensate, but that the View the MathML source condensate remains unaffected up to the chiral order under consideration. We discuss the implication of the suppressed View the MathML source condensate for flavor-dependent chiral symmetry restoration in dense matter.
