Abstract
We examine the large branching ratio for the process B→η′K from the standpoint of R parity violating supersymmetry. We have given all possible contributions to B→η′K amplitudes. We find that only two pairs of λ′-type couplings can solve this problem after satisfying all other experimental bounds. We also analyze those modes where these couplings can appear, e.g., B±→π±K0, , B±→φK± etc., and predict their branching ratios. Further, one of these two pairs of couplings is found to lower the branching ratio of B±→φK±, thereby allowing larger ξ≡1/Nc. This allows us to fit B±→ωK± and B±→ωπ±, which could not be done in the SM framework.
