Non-factorizable Contributions to B → ππ Decays
We investigate to what extent the experimental information on B → ππ branching fractions and CP asymmetries can be used to better understand the QCD dynamics in these decays. For this purpose we decompose the independent isospin amplitudes into factorizable and non-factorizable contributions. The former can be estimated within the framework of QCD factorization for exclusive B decays. The latte...
متن کاملNon-factorizable contributions in B decays revisited
B̄ → Dπ, Dπ, J/ψK̄ and J/ψπ decays are studied by decomposing their amplitude into a sum of factorizable and non-factorizable ones. The former is estimated by using the naive factorization while the latter is calculated by using a hard pion approximation in the infinite momentum frame. Although experiments provide only upper bounds of the branching ratios for the color suppressed B̄0 → D0π0 and D∗...
متن کاملNon-factorizable contributions in hadronic weak decays of charm mesons
Two body decays of charm mesons are studied by describing their amplitude in terms of a sum of factorizable and non-factorizable ones. The former is estimated by using a naive factorization while the latter is calculated by using a hard pseudo-scalar-meson approximation. The hard pseudo-scalar-meson amplitude is given by a sum of the so-called equal-time commutator term and surface term which c...
متن کاملYITP-99-65 Non-factorizable contributions in B decays ∗
First of all, ¯ B → Dπ and D * π decays are studied phenomenologically and possible lower bounds of the branching ratios, B(¯ B 0 → D 0 π 0) and B(¯ B 0 → D * 0 π 0), are estimated from existing experimental data on branching ratios for the ¯ B → Dπ and D * π decays. Then, ¯ B → Dπ, D * π, J/ψ ¯ K and J/ψπ decays are studied by decomposing their amplitude into a sum of factorizable and non-fact...
متن کاملNon-factorizable contributions to deep inelastic scattering at large x
We use soft-collinear effective theory (SCET) to study the factorization properties of deep inelastic scattering in the region of phase space where (1− x) ∼ ΛQCD/Q. By applying a regions analysis to loop diagrams in the Breit frame, we show that the appropriate version of SCET includes anti-hard-collinear, collinear, and softcollinear fields. We find that the effects of the soft-collinear field...
