Abstract
We examine the charmless hadronic B decay modes in the context of R-parity violating (Rslash p) supersymmetry. We try to explain the large branching ratio (compared to the Standard Model (SM) prediction) of the decay B ± → η′K ±. There exist data for other observed η (1) modes and among these modes, the decay B 0 → ηK* 0 is also found to be large compared to the SM prediction. We investigate all these modes and find that only two pairs of Rslash p coupling can satisfy the requirements without affecting the other B → P P and B → V P decay modes barring the decay B → ΦK. From this analysis, we determine the preferred values of the Rslash p couplings and the effective number of color N c. We also calculate the CP asymmetry for the observed decay modes affected by these new couplings.
