Kaon mass in dense matter

The variation of kaon mass has been investigated in dense nuclear matter, both symmetric as well as asymmetric matter in beta equilibrium. The baryon interaction has been included by means of the nonlinear Walecka model and the interaction of kaons with baryons has been incorporated through the Kaplan-Nelson model. A self-consistent calculation up to the fourth power of 1f has been carried out. We find that the loop diagrams tend to lower the kaon condensation point for decreasing values of a3ms, i.e., higher strangeness content of the proton.
