Nonleptonic B decays into a charmed tensor meson
In the framework of the factorization and the heavy quark effective theory, B → D 2π modes are analyzed. We adopt the result from the QCD sum rule calculation for the hadronic matrix elements at leading order of ΛQCD/mQ and αs. The QCD sum rule results are well compatible with the current data, with the prediction on the branching ratios B(B̄0 → D 2 π) = 8.94 × 10−4 and B(B− → D∗0 2 π) = 9.53 × ...
متن کاملThreshold Resummation in B → X c l ν l Decays
We compute the QCD form factor resumming threshold logarithms in B → Xc+ l+νl decays to next-to-leading logarithmic approximation. We present an interpolation formula including soft as well as collinear effects softened by the non-vanishing charm mass which, in the N -space, reads: σN = exp ∫ 1 0 dy [
متن کاملNonleptonic B Decays and Rare Decays
We review selected topics in the field of nonleptonic and rare B meson decays. We concentrate in particular on exclusive channels, discussing recent developments based on the concepts of factorization in QCD and the heavy-quark limit. 1
متن کاملNonfactorizable soft gluons in nonleptonic heavy meson decays
We include nonfactorizable soft gluon corrections into the perturbative QCD formalism for exclusive nonleptonic heavy meson decays, which combines factorization theorems and effective field theory. These corrections are classified according to their color structures, and exponentiated separately to complete the Sudakov resummation up to next-to-leading logarithms. The nonfactorizable contributi...
متن کاملQcd-improved Factorization in Nonleptonic B Decays
Nonleptonic decays ofB mesons have attracted a lot of attention recently since they were observed experimentally in CLEO, BaBar and BELLE. These decays are important in extracting the information on the Cabibbo-KobayashiMaskawa (CKM) matrix elements and CP violation. On the theoretical side, it is the least understood area. Since nonleptonic decays involve nonperturbative effects such as final-...
