摘要The density dependent relativistic mean field (DDRMF) model in the new parametrization used recently is extended to investigate antikaon condensation and in-medium (anti)kaon production in beta equilibrium nuclear matter, and the obtained results are compared for different models. Our results show that the mean critical density for antikaon condensation is approximate to2.8rho(0) in the DDRMF model with the two model parameter sets and in the nonlinear sigma-omega model with the parameter set Tm1, while a little larger critical density 3.3rho(0) is obtained in chiral perturbation theory. The subthreshold energies for (anti)kaon production are calculated, and indicate that the in-medium effects predicted by the DDRMF model are essential for explaining the antikaon enhanced production, while kaon production rates are possibly enhanced only in the high density region. As an application for beta equilibrium nuclear matter, the masses against the central densities of neutron stars are studied in the DDRMF model too.
