We show that, in the heavy quark limit, the hadronic matrix elements that enter B meson decays into two light mesons can be computed from first principles, including {open_quotes}nonfactorizable{close_quotes} strong interaction corrections, and expressed in terms of form factors and meson light-cone distribution amplitudes. The conventional factorization result follows in the limit when both power corrections in 1/m{sub b} and radiative corrections in {alpha}{sub s} are neglected. We compute…

QCD factorization for B → ππℓν decays at large dipion masses

A bstractWe introduce a factorization formula for semi-leptonic b → u transitions in the exclusive decay mode B−→π+π−ℓ−ν¯ℓ$$ {B}^{-}\to {\pi}^{+}{\pi}^{-}{\ell}^{-}{\overline{\nu}}_{\ell } $$ in the

In this paper, we calculate the decay rate and CP asymmetry of the ${B}_{s}\ensuremath{\rightarrow}{\ensuremath{\pi}}^{+}{\ensuremath{\pi}}^{\ensuremath{-}}$ decay in the perturbative QCD approach

Two-body non-leptonic heavy-to-heavy decays at NNLO in QCD factorization

A bstractWe evaluate in the framework of QCD factorization the two-loop vertex corrections to the decays B¯s→Ds∗+L−$$ {\overline{B}}_{(s)}\to {D}_{(s)}^{\left(\ast \right)+}{L}^{-} $$ and Λb → Λc+L−,

W radiative decay to heavy-light mesons in HQET factorization through O(αs)

Analogous to the non-relativistic Quantum Chromodynamics (NRQCD) factorization for heavy quarkonium exclusive production, in this work we propose to employ the heavy quark effective theory (HQET)

Nonleptonic two-body decays of the B c meson in the light-front quark model and the QCD factorization approach

CP-Violation in B(q) Decays and Final State Strong Phases

Using the unitarity, SU(2) and C invariance of hadronic interactions, the bounds on final state phases are derived. It is shown that values obtained for the final state phases relevant for the direct

Nonfactorizable contributions to B meson decays into charmonia

We analyze the B{yields}(J/{psi},{chi}{sub c0},{chi}{sub c1},{eta}{sub c})K{sup (}*{sup )} decays, which have small or even vanishing branching ratios in naive factorization assumption (FA). We

Heavy exotic scalar meson Tbb;u¯s¯−

The spectroscopic parameters and decay channels of the scalar tetraquark $ T_{bb;\overline{u}\overline{s}}^{-}$ (in what follows $T_{b:\overline{s} }^{-} $) are investigated. The mass and coupling of

Final state interactions in hadronic B decays

There exist many experimental indications that final-state interactions (FSIs) may play a prominent role not only in charmful B decays but also in charmless B ones. We examine the final-state
