Abstract

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, SφK0, Sη′K0, S K0π0 which are compared to SJ/ψK0. We also show that several Bs decay modes may help to resolve the ambiguities in such an analysis. Through combining analysis with the time-dependent CP asymmetries of Bs decay modes such as Bs → φη′, Bs → η′π0 and B s → K00, we can determine where the new CP phases precisely come from.
