Decay coupling constants sum rules for dibaryon octet into two baryon octets with λ8 first order SU(3) symmetry breaking

The SU(3) octet states with baryon number B = 2, hexaquark dibaryons, are considered. Strong decay coupling constants sum rules for dibaryon octet into two ordinary baryon octets with λ8 first order SU(3) symmetry breaking are given. An SU(4) extension of the analysis is commented upon. Possibilities for the experimental observation of multibaryon and anti-multibaryon states are pointed out.
