Hadron Dynamics in Meson-Baryon Few-Body Systems

Conference paper
Part of the Few Body Systems book series (FEWBODY, volume 13)


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. Furthermore, comments are made on the recent progress concerning the πNN — ηNN quasibound state and the two-nucleon resonances.
