Abstract
Ehime approach on effective one-boson-exchange potentials (OBEP) for YN and YY interactions is reviewed. The potentials use the SU(3) invariant framework for the pseudoscalar, scalar and vector nonet-mesons and also employ additional SU(3) violating elements. Successful results on (1) ΛN and ΛΛ interactions, (2) ΞN, Ξ-nucleus, and ΞΞ interactions and (3) ΛN-ΣN coupled interactions are reviewed. The Ehime results are compared with the Nijmegen (SC97f) ones and discriminating points are discussed.
