  The variation of kaon mass in dense, charge-neutral baryonic matter at
beta-equilibrium has been investigated. The baryon interaction has been
included by means of nonlinear Walecka model, with and without hyperons and the
interaction of kaons with the baryons has been incorporated through the
Nelson-Kaplan model. A self-consistant, one-loop level calculation has been
carried out. We find that at the mean field level, the presence of the hyperons
makes the density-dependence of the kaon mass softer. Thus, the kaon
condensation threshold is pushed up in the baryon density. The loop diagrams
tend to lower the kaon condensation point for lower values of $a_3 m_s$. We
also find that the S-wave kaon-nucleon interaction plays the dominant role in
determining the on-set of kaon condensation and the contribution of the P-wave
interaction is insignificant.
