Abstract

We have investigated the prototype of K̄-nuclear systems, ppK ^-, with a realistic NN potential and effective local K̄ potentials based on chiral SU(3) dynamics. Including estimates of theoretical uncertainties, we find that ppK^- is not deeply bound, with a total binding energy = 19 ± 3 MeV and mesonic decay width between about 40 and 70 MeV. The K̄N (I = 0) component in the ppK^- compound is of a similar structure as the K̄N two-body quasibound state embedded in the πΣ continuum.
