Abstract:

Structures of the effective Hamiltonian describing B(1/2⁺, 20^′) →B(1/2⁺, 20^′)+P(0^-, 15) are investigated in case of 15-spurion dominance. It is shown that the duality requirement imposed on connected-line diagrams with 4- and 4^*-lines (“4^* rule”) is consistently applied to lead to favourable amplitudes of P- as well as S-waves of ordinary hyperon decays.
