Kaonic nuclei studied based on a new framework of Antisymmetric Molecular Dynamics

Abstract

We have developed a new framework of Antisymmetrized Molecular Dynamics (AMD), to adequately treat the I=0 K̄N interaction, which is essential to study kaonic nuclei. The improved points are 1) pK${}^{-}$/nK̄${}^0$ mixing and 2) total spin and isospin projections. These improvements enable us to investigate various kaonic nuclei (ppnK${}^{-}$, pppK${}^{-}$, pppnK${}^{-}$, ${}^6$BeK${}^{-}$ and ${}^9$BK${}^{-}$) systematically. We have found that they are deeply bound and extremely dense with a variety of shapes.
