Light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading order twist-4 corrections are used in Ref.…”

The form factors of the weak B s transitions to the ground state and orbitally excited strange mesons are calculated in the framework of the QCD-motivated relativistic quark model based on the quasipotential approach. These form factors are expressed through the overlap integrals of meson wave functions found in their mass spectrum evaluations. The momentum dependence of the form factors is determined in the whole accessible kinematical range without any additional assumptions and extrapolations. Relativistic effects, including the wave function transformation from the rest to a moving reference frame as well as contributions of the intermediate negative-energy states, are consistently taken into account. The calculated form factors are used for the evaluation of the charmless semileptonic decay rates and two-body nonleptonic B s decays in the factorization approximation. The obtained results are confronted with previous predictions and available experimental data.

“…Exclusive B q (q = u, d, s) meson decays, especially B q → V V modes, where V stands for a light vector meson (ρ, K * , ω, φ), have aroused a great deal of interest for both theorists [1][2][3][4][5][6][7][8][9] and in experiments [10]. In contrast to the scalar and pseudoscalar mesons, vector mesons can be produced in several polarization states.…”

Improved estimates of theB(s)→VVdecays in perturbative QCD approach

We reexamine the branching ratios, CP -asymmetries, and other observables in a large number of B q → V V (q = u, d, s) decays in the perturbative QCD (PQCD) approach, where V denotes a light vector meson (ρ, K * , ω, φ). The essential difference between this work and the earlier similar works is of parametric origin and in the estimates of the power corrections related to the ratio) (m V and m B denote the masses of the vector and B meson, respectively). In particular, we use up-to-date distribution amplitudes for the final state mesons and keep the terms proportional to the ratio r 2 i in our calculations. Our updated calculations are in agreement with the experimental data, except for a limited number of decays which we discuss. We emphasize that the penguin annihilation and the hard-scattering emission contributions are essential to understand the polarization anomaly, such as in the B → φK * and B s → φφ decay modes. We also compare our results with those obtained in the QCD factorization (QCDF) approach and comment on the similarities and differences, which can be used to discriminate between these approaches in future experiments.
