In this paper, we study nonleptonic charmless B decays to two light pseudoscalar mesons within the frame of QCD factorization, including the contributions from the chirally enhanced power corrections and weak annihilation. Predictions for the CP-averaged branching ratios and CP-violating asymmetries are given. Within the reasonable range of the parameters, we find that our predictions for the branching ratios of B-->PP are consistent with the present experimental data. But because of the…

An analysis of B meson decays to two light pseudoscalar nonets with |ΔS| = 1 in QCD factorization approach
We have performed a numerical analysis of branching ratios and direct CP-asymmetries of B meson decays to two light pseudoscalar nonets with |ΔS| = 1 using QCD improved factorization. The parameters
BVDecays with the QCD Factorization Approach
B c meson is at least at the order of α4 s via ij → B(∗)+ c + bc, where the gluon-gluon fusion mechanism is dominant at Tevatron and LHC [2]. The B c meson is difficult to produce experimentally, but
Study of B ∗ 0 d , s → D + d , s M − Decays with QCD Factorization Approach
Thanks to the fruitful running of BABAR, Belle, CDF, and D0 experiments in the past decade, most of the B meson decays with branching fractions ≳O(10−7) are measured precisely, which provide a very
Factorization and hadronic B decays in the heavy quark limit
Recent theoretical investigations (Beneke M et al 1999 Phys. Rev. Lett. 83 1914) of two-body hadronic B decays have provided justification, at least to order αs, for the use of the factorization
Study of the Υ(1S) → DP decays
Inspired by the potential prospects of high-luminosity dedicated colliders and the high enthusiasms in searching for new physics in the flavor sector at the intensity frontier, the Υ(1S) → D−π+, D...
