| Abstract: | This work employs the Density-Dependent Relativistic Hadron (DDRH) model in a Bayesian framework to study dense matter in neutron stars with antikaon ($K^-$ and $\bar{K}^0$) condensation. By constraining parameters through nuclear properties and observations of pulsars and the GW170817 event, we estimate the antikaon potential to be around $-129.36$ MeV, aligning with values from previous studies. Antikaon condensation notably softens the equation of state (EOS), reducing the maximum mass of neutron stars to around 2M$_\odot$ and lowering the speed of sound. While $K^-$ condensation is unlikely in standard neutron stars, both $K^-$ and $\bar{K}^0$ are feasible in higher-mass stars, revealing insights into the EOS and neutron star properties in dense matter. |
