Abstract

A phenomenological analysis based on the published branching fractions and CPCP asymmetry observables of the BKπB\to K\pi, BππB\to\pi\pi and BKKB\to KK dataset is performed. The amplitude decomposition by the topological diagrams and the SU(3)SU(3) irreducible representation is used. The result of the global fit can be interpreted as a solution to the ``BKπB\to K\pi puzzle''. The obtained precision enables to test a SU(3)SU(3)-based sum rule showing 6σ6\sigma discrepancy with the expectation value in the Standard Model scenario. To improve the obtained results the main effort should concentrate on the B0K0π0B^0\to K^0\pi^0 measurements.
