Abstract: According to the Coleman-Glashow null theorem if all the symmetry breaking effects belong to the same regular representation (octet in the case of SU(3) and 15 in the case of SU(4) and are generated in a tadpole type mechanism, the strangeness changing (charm changing) weak transitions generated through the S6 (S9) tadpole must vanish. Exploiting this null result, relations between the BBP coupling constants are obtained, which leads to the coupling constants in terms of two parameters and baryon masses. Fixing these two parameters (g NNπ and g ɅƩπ) from experiments, the remaining coupling constants are estimated.
