• The coupling constants of strong interactions are given by considering Y's and other experimental results which include Ξ. It is shown that Y_1 (1385 Mev), Y_0 (1405 Mev) and Y_2 (1550 Mev) can be regarded as analogues of N_3, the (3-3) resonance. If the spin-parity of Y_0 is P_<3/2> it may be concluded that g^2_<ΣΣπ>≈0,g^2_<ΛΣπ>≈g^2_<NNπ>, g^2_<ΣNK>≈0 and g^2_<ΛNK>=1~3, where g's ps-coupling constants of the verticies indicated by the suffices. In this case it follows necessarily that the resonant state with the isotopic spin 2 appears in Σ-π scattering, but it may have a rather broad peak. The coupling constants of π and K to Ξ are also discussed. And then a possible choice for the coupling constants are obtained along the Miyazawa, Nakano and Umezawa hypothesis.
