Recently, the standard model predictions for the B-meson hadronic decays, (B) over bar (0) -> D-(*)+ K- and (B) over bar (0)((s)) -> D-(s)((*)+) pi(-), have been updated based on the QCD factorization approach. This improvement sheds light on a novel puzzle in the B-meson hadronic decays: there are mild but universal tensions between data and the predicted branching ratios. Assuming the higher-order QCD corrections are not huge enough to solve the tension, we examine several new physics interpretations of this puzzle. We find that the tension can be partially explained by a left-handed W0 model, which can be compatible with other flavor observables and collider bounds.
