THE PSEUDOSCALAR BBP COUPLINGS IN THE QUARK-MODEL

Employing the null result of Coleman and Glashow (1964), and of Feinberg, Kabir and Weinberg, that the strangeness (charm)-changing weak effects generated through the tadpole S6(S9) must vanish, the authors obtain relations among the quark-quark-pion (kaon) coupling constants. They use these relations and the additive quark model to obtain the pseudoscalar BBP strong couplings. The results are in good agreement with available experimental values.
