We analyze the CP asymmetries of B→φK and B→η(′)K modes in the QCD improved factorization framework. The phenomenological parameters are determined from the global fit for the available B→PP and VP modes (without the subprocess b→ss̄s). The large negative sin(2φ1)φKs and the large branching ratio for B±→η′K± can be simultaneously explained in the context of R-parity conserving SUGRA models and R-parity violating SUSY models satisfying all possible experimental data. The SUSY models are also consistent with the available data on the CP asymmetries for different B ±(0)→φK±(0) and B ±(0)→η(′)K±(0) modes.
