“…We also give the predictions on the sum of the CP-averaged branching ratios of B0 → π − ρ + and B0 → π + ρ − and the other three B (s) decays in table I and table VI. In order to compare with QCDF approach [10,41,42,43,44,45] and PQCD approach [46,47,48,49,50,51,52,53,54,55,56,57,58], we also collect their results in these tables, together with the experimental data available at HFAG [39].…”

We provide the analysis of charmless two-body B → V P decays under the framework of the softcollinear-effective-theory (SCET), where V (P ) denotes a light vector (pseudoscalar) meson. Besides the leading power contributions, some power corrections (chiraly enhanced penguins) are also taken into account. Using the current available B → P P and B → V P experimental data on branching fractions and CP asymmetry variables, we find two kinds of solutions in χ 2 fit for the 16 nonperturbative inputs which are essential in the 87 B → P P and B → V P decay channels. Chiraly enhanced penguins can change several charming penguins sizably, since they share the same topology.However, most of the other non-perturbative inputs and predictions on branching ratios and CP asymmetries are not changed too much. With the two sets of inputs, we predict the branching fractions and CP asymmetries of other modes especially Bs → V P decays. The agreements and differences with results in QCD factorization and perturbative QCD approach are analyzed. We also study the time-dependent CP asymmetries in channels with CP eigenstates in the final states and some other channels such as B0 /B 0 → π ± ρ ∓ and B0s /B 0 s → K ± K * ∓ . In the perturbative QCD approach, the (S − P )(S + P ) penguins in annihilation diagrams play an important role. Although they have the same topology with charming penguins in SCET, there are many differences between the two objects in weak phases, magnitudes, strong phases and factorization properties.

We give an overview of the experimental measurements and the theoretical understanding of the branching fractions and CP -violating asymmetries of charmless B-meson decays. Most experimetal results are from the BABAR and Belle experiments during the past decade. The global features of these experimental results are typically well described by the QCD-motivated theories such as QCD factorization, pQCD and soft-collinear effective theory. The agreement between theory and experiment is generally satisfactory, though there remain some unsolved puzzles that pose a great challenge to both theorists and experimentalists.

In this article, we calculate the branching ratios of B → K * 0 (1430)K decays by employing the perturbative QCD (pQCD) approach at leading order. We perform the evaluations in the two scenarios for the scalar meson spectrum. We find that (a) the leading order pQCD predictions for the branching ratio Br(B + → K +K * 0 (1430) 0 ) which is in good agreement with the experimental upper limit in both scenarios, while the pQCD predictions for other considered B → K * 0 (1430)K decay modes are also presented and will be tested by the LHC experiments; (b) the annihilation contributions play an important role in these considered decays, forfor example, which are found to be (1 − 4) × 10 −6 .
