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