Kaon Condensation in Dense Stellar Matter

This article combines two talks given by the authors and is based on works done in collaboration with G.E. Brown and D.-P. Min on kaon condensation in dense baryonic medium treated in chiral perturbation theory using heavybaryon formalism. It contains, in addition to what was recently published, astrophysical backgrounds for kaon condensation discussed by Brown and Bethe, a discussion on a renormalization-group analysis to meson condensation worked out together with H.K. Lee and S.-J. Sin, and the recent results of K. M. Westerberg in the bound-state approach to the Skyrme model. Negatively charged kaons are predicted to condense at a critical density 2 <∼ ρ/ρ0 <∼ 4, in the range to allow the intriguing new phenomena predicted by Brown and Bethe to take place in compact star matter. Based on talks given by CHL and MR at International Workshop on Nuclear and Particle Physics, “Chiral Dynamics in Hadrons and Nuclei”, Feb. 6 ∼ Feb.10, 1995, Seoul Nat’l University, Seoul, Korea
