Abstract

We present a systematic method to extract each standard model (SM)-{\it like} hadronic parameter as well as new physics parameters in analytic way for BKπB\to K\pi decays. Using the analytic method to the currently available experimental data, we find two possible solutions analytically equivalent: one showing the large SM-{\it like} color-suppressed tree contribution and the other showing the large SM-{\it like} EWP contribution. The magnitude of the NP amplitude and its weak phase are quite large. For instance, we find PNP/P=0.39±0.13|P^{NP}/P| = 0.39\pm0.13, ϕNP=91±15\phi^{NP}=91^\circ\pm15^\circ and δNP=8±27\delta^{NP}=8^\circ\pm27^\circ, which are the ratio of the NP-to-SM contribution, the weak and the relative strong phase of the NP amplitude, respectively.
