“…This error at present prevents this observable from providing a stringent test of our framework. Such test will however be possible with improvements on fits to the unitarity triangle using only observables realistically unaffected by new physics, such as γ from B → DK ( * ) (see in particular [86][87][88]). This highlights the well-known importance of improvements in such 'standard-candle' measurements.…”

One of the greatest challenges for models of b → s anomalies is the necessity to produce a large contribution to a quark times a lepton current, J q × J , and to avoid accordingly large contributions to flavour-changing J q ×J q and J ×J amplitudes, which are severely constrained by data. We consider a gauged horizontal symmetry involving the two heaviest generations of all left-handed fermions. In the limit of degenerate masses for the horizontal bosons, and in the absence of mixing between the two heavier generations and the lighter one, such symmetry would make J q × J q and J × J amplitudes exactly flavourdiagonal. Mixing with the first generation is however inescapable due to the CKM matrix, and the above mechanism turns out to be challenged by constraints such as D 0 −D 0 mixing. Nonetheless, we show that a simultaneous description of all data can be accomplished by simply allowing for non-degenerate masses for the horizontal bosons. Such scenario predicts modifications in several processes that can be tested at present and upcoming facilities. In particular, it implies a lower and upper bound for B(B → Kµ ± τ ∓), an asymmetry between its two charge conjugated modes, and well-defined correlations with LFV in τ decays.

“…Since the Belle Collaboration's announcement [14], much work [24][25][26][27][28] has emerged for the twobody hadronic B decays involving D Ã 0 . By studying the three-body hadronic B meson decays involving D Ã 0 , one could provide the constraint on the unitary triangle [29][30][31][32] and probe the inner structure of the intermediate resonances. In Ref.…”

We study the quasi-two-body decays B → PD Ã 0 ð2400Þ → PDπ with P ¼ ðπ; K; η; η 0 Þ in the perturbative QCD factorization approach. The predicted branching fractions for the considered decays are in the range of 10 −9 -10 −4 . The strong Cabibbo-Kobayashi-Maskawa (CKM) suppression factor R CKM ≈ λ 4 ðρ 2 þη 2 Þ ≈ 3 × 10 −4 results in the great difference of the branching ratios for the decays with D Ã 0 andD Ã 0 as the intermediate states. The ratio RDÃ0 0 between the decays B 0 →D Ã0−0.005 , consistent with the flavor-SUð3Þ symmetry result. The ratio for the branching fractions is found to be 1.10 þ0.05 −0.02 between BðB 0 s → D Ãþ 0 K − → D 0 π þ K − Þ and BðB 0 → D Ãþ 0 π − → D 0 π þ π − Þ and to be 1.03 þ0.06 −0.07 between BðB 0 s →D Ã0 0K 0 → D − π þK0 Þ and 2BðB 0 →D Ã0 0 π 0 → D − π þ π 0 Þ. The predictions in this work can be tested by the future experiments.
