Multi-Antikaonic Nuclei and Kaon Condensation in Dense Matter.

The structure of multi-antikaonic nuclei (MKN) is investigated in a relativistic mean-field theory coupled with the nonlinear K- field by the use of effective chiral Lagrangian. The effects of the Λ(1405) range terms on the structure of the MKN are taken into account. It is shown that baryon number density exceeds three times the normal saturation density in the central region of the MKN that a neutron skin structure becomes remarkable as the number of the embedded K- mesons increases. The similarity difference between the MKN kaon condensation in neutron stars are discussed. [ABSTRACT FROM AUTHOR]
