    AnotáciaThe kaon polarization operator in dense baryonic matter of arbitrary isotopic composition is calculated including s- and p-wave kaon-baryon interactions. The regular part of the polarization operator is extracted from the realistic kaon-nucleon interaction based on the chiral and 1/N-c expansion. Contributions of Lambda(1116), Sigma(1195), Sigma*(1385) resonances are taken explicitly into account in the pole and regular terms with the inclusion of mean-field potentials. The baryon-baryon correlations are incorporated and fluctuation contributions are estimated. Results are applied for K- in neutron star matter. Within our model a second-order phase transition to the s-wave K- condensate state occurs at rho(c)greater than or similar to4rho(0) with baryon-baryon correlations included. We show that a second-order phase transition to the p-wave K- condensate state may occur at densities rho(c)similar to(3-5)rho(0) dependent on the parameter choice. We demonstrate that a first-order phase transition to a proton-enriched (approximately isospin-symmetric) nucleon matter with a p-wave K- condensate can occur at smaller densities, rholess than or similar to2rho(0). The transition is accompanied by the suppression of hyperon concentrations.
