### Abstract

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(2φ_{1})_{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.
