QCD-factorization amplitudes from flavour symmetries: beyond the $SU(3)$ symmetric case

Wen-Sheng Fang, Tobias Huber, Xin-Qiang Li +2

Using experimental information on branching ratios as well as direct and mixing-induced CP asymmetries, we perform a data-driven analysis of charmless non-leptonic $B\to PP$ decay…
