Systematic investigation of possibilities for new physics effects in b → s penguin processes

Although recent experimental results in b → s penguin process seem to be roughly consistent with the standard model predictions, there may be still large possibilities of new physics hiding in these processes. Therefore, here we investigate systematically the potential new physics effects that may appear in time-dependent CP asymmetries of B → φK⁰, B → η′K⁰ and B → K⁰π⁰ decay modes, by classifying the cases for the values of the mixing-induced indirect CP asymmetries, S_φK0, S_η′K0, S _K0π0 which are compared to S_J/ψK0. We also show that several B_s decay modes may help to resolve the ambiguities in such an analysis. Through combining analysis with the time-dependent CP asymmetries of B_s decay modes such as B_s → φη′, B_s → η′π⁰ and B _s → K⁰K̄⁰, we can determine where the new CP phases precisely come from.
