CP asymmetries of B→φK and B→η (′)K decays using a global fit in QCD factorization

We analyze the CP asymmetries of B --> phiK and B-->eta((1)) K modes in the QCD improved factorization framework. The phenomenological parameters are determined from the global fit for the available B --> P P and V P modes (without the subprocess b --> s (s) over bars). The large negative sin(2phi(1))(phiKs) and the large branching ratio for B+/--->eta' 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)-->phiK(+/-(0)) and B+/- (0)-->eta(')K+/-(0) modes. (C) 2004 Elsevier B.V. All rights reserved.
