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 slashed R signp contributions to B → η′K amplitudes. We find that only two pairs of λ′-type slashed R signp 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±,0 → K * ±,0η(′), 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 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. © 1999 Elsevier Science B.V. All rights reserved.
