Abstract

We examine the large branching ratio for the process BηKB\to \eta^{\prime} K from the standpoint of R parity violating supersymmetry. We have given all possible RpR_p violating contributions to BηKB\to \eta^{\prime} K amplitudes. We find that only two pairs of λ\lambda^{\prime}-type RpR_p violating couplings can solve this problem after satisfying all other experimental bounds. We also analyze those modes where these couplings can appear, {\em e.g.}, B±π±K0B^\pm \to \pi^{\pm}K^0, B±,0K±,0η()B^{\pm,0} \to K^{*\pm,0} \eta^{(\prime)}, B±ϕK±B^{\pm} \to\phi K^{\pm} etc., and predict their branching ratios. Further, one of these two pairs of couplings is found to lower the branching ratio of B±ϕK±B^{\pm}\to\phi K^\pm, thereby allowing larger ξ1Nc\xi\equiv{1\over N_c}. This allows us to fit B±ωK±B^{\pm}\to \omega K^{\pm} and B±ωπ±B^{\pm}\to \omega \pi^{\pm}, which could not be done in the SM framework.
