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…

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)

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
