The “ $$B\rightarrow K\pi $$ B → K π puzzle”: a new perspective
Abstract A phenomenological analysis based on the published branching fractions and CP asymmetry observables of the $$B\rightarrow K\pi $$ B → K π , $$B\rightarrow \pi \pi $$ B → π π and $$B\rightarrow KK$$ B → K K dataset is performed. The amplitude decomposition by the topological diagrams and the...

| description | Abstract A phenomenological analysis based on the published branching fractions and CP asymmetry observables of the $$B\rightarrow K\pi $$ B → K π , $$B\rightarrow \pi \pi $$ B → π π and $$B\rightarrow KK$$ B → K K 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 “ $$B\rightarrow K\pi $$ B → K π puzzle”. The obtained precision enables to test a SU(3)-based sum rule showing $$6\sigma $$ 6 σ discrepancy with the expectation value in the Standard Model scenario. To improve the obtained results the main effort should concentrate on the $$B^0\rightarrow K^0\pi ^0$$ B 0 → K 0 π 0 measurements. |
