Abstract

We have investigated the prototype kaonic nucleus, ppK̄, 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 K̄N interaction which is energydependent and includes both s- and p-wave interactions. We find that no self-consistent solutions exist when the range parameter of the KN interaction is less than 0.67 fm. Due to the strong repulsion of the NN interaction at short distance, the two nucleons in ppK̄ keep a distance of about 1.2 fm and the total binding energy of ppK̄ does not exceed about 50 MeV in the scope of our current analysis.
