摘要：
Using one-hadron-exchange potentials which describe consistently the baryon–baryon (NN, YN and YY) and meson–baryon (π N and KN) interactions, we discuss properties of the S-wave Kbar-hyperon interactions. Solving the coupled-channel πΞ-KbarΛ-KbarΣ problem, we obtain the possible existence of an S-wave resonance (a quasibound state of KbarΛ) below the KbarΛ threshold. A KbarΞ bound state with I = 0 is also predicted.
