Abstract:

We investigate deeply bound kaonic nuclei, ppnK^- and ⁸BeK^-, with Antisymmetrized Molecular Dynamics. We use a phenomenological KN potential which reproduces Λ(1405) as a I=0 bound state of KN. According to our calculations both systems are very deeply bound. ppnK^- is bound by -106 MeV below the ³He+K^- threshold and ⁸BeK^- is bound by -124 MeV below the ⁸Be+K^- threshold. They are strikingly shrunk and are highly dense and cold. Especially an interesting deformation can be seen in ⁸BeK^-.
