摘要：

Using one-hadron-exchange potentials which describe consistently the baryon-baryon (NN, YN and YY) and meson-baryon (pi N and KN) interactions, we discuss properties of the S-wave K (bar) -hyperon interactions. Solving the coupled-channel pi I-K (bar) I >-K (bar) I pound problem, we obtain the possible existence of an S-wave resonance (a quasibound state of K (bar) I >) below the K (bar) I > threshold. A K (bar) I bound state with I = 0 is also predicted.
