Abstract
We have investigated the prototype kaonic nucleus, ppK -, using the method of Antisymmetrized Molecular Dynamics (AMD). In the present study we use a realistic NN potential with strongly repulsive core, and a Chiral SU(3)-based \( \bar K \) N interaction which is energy-dependent and includes both s- and pwave interactions. We find that no self-consistent solutions exist when the range parameter of the \( \bar K \) N interaction is less than 0.67 fm. Due to the strong repulsion of the NN interaction at short distance, the two nucleons in ppK - keep a distance of about 1.2 fm and the total binding energy of ppK - does not exceed about 50 MeV in the scope of our current analysis.
