✦ Synopsis

The nonmesonic decay moded of A in nulear matter, AN ~ NN, and production of A in proton-neutron scattering, pn ~ An, are studied theoretically. The weak transition of baryon is described by the one meson exchange mechanism and the direct quark-quark interaction mechanism.

Quark-chiral field interaction is studied in terms of the linear realization of the Lagrangian which is invariant under the SU(3)L Γ— SU(3)R infinitesimal transformation and then is applied to the hyperon-nucleon scattering calculation in the framework of RGM. It is shown that the SU(3) chiral scalar
