Analytic resolution of puzzle in B→Kπ decays
چکیده انگلیسی
We present a systematic method to extract each Standard Model (SM)-like hadronic parameter as well as new physics parameters in analytic way for B→Kπ decays. Using the analytic method to the currently available experimental data, we find two possible solutions physically equivalent: one showing the large SM-like color-suppressed tree contribution and the other showing the large SM-like electroweak penguin contribution. The magnitude of new physics (NP) amplitude and its weak phase are quite large. For instance, we find |PNP/P|=0.39±0.13, ϕNP=91°±15° and δNP=8°±27°, which are the ratio of the NP to the SM penguin contribution, the weak and the relative strong phase of the NP amplitude, respectively.
