In light of the recent experimental data from B factories, We try to explain the large branching ratio (compared to the Standard Model prediction) of the decay B± → η′ K± in the context of R-paxity violating (Rp ) supersymmetry. We investigate other observed η(′) modes and find that only two pairs of Rp coupling can satisfy the requirements without affecting the other B → PP and B → V P decay modes except the mode B → φK. We also calculate the CP asymmetry for the observed decay modes affected by the new couplings.
