YITP-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 کاملB Decays to D
The e + e − annihilation data recorded with the BABAR detector has been used to study B 0 decays to D (*)+ s and D * − mesons. The production fraction of inclusive D (*)+ s and the corresponding momentum spectra have been determined. Exclusive decays B 0 → D * − D (*)+ s have been identified with a partial reconstruction technique and their branching ratios have been measured. Fully reconstruct...
متن کاملUsing B 0 s Decays to Determine the CP Angles α and γ
Dighe, Gronau and Rosner have shown that, by assuming SU(3) flavor symmetry and first-order SU(3) breaking, it is possible to extract the CP angles α and γ from measurements of the decay rates of B 0 d (t) → π + π − , B 0 d → π − K + and B + → π + K 0 , along with their charge-conjugate processes. We extend their analysis to include the SU(3)-related decays B 0 s → π + K − , B 0 s (t) → K + K −...
متن کاملOf D - Meson Dalitz Plot Analyses
The formalism of Dalitz-Plot analysis is reviewed in the preceding note. Recent studies of multi-body decays of charm mesons probe a variety of physics including γ/φ 3 , D 0 –D 0 mixing, searches for CP violation, doubly Cabibbo-suppressed decays, and properties of S-wave ππ, Kπ, and KK resonances. In the following, we discuss: (1) D 0 → K 0 S π + π − ; (2) doubly Cabibbo-suppressed decays; and...

The results of several studies of charmed mesons and baryons at BABAR are presented. First, searches for the rare decays D 0 → l + l − are presented and new upper limits on these processes are established. Second, a measurement of the branching fraction of the isospin-violating hadronic decay D * s (2112) + → D + s π 0 relative to the radiative decay D * s (2112) + → D + s γ is made. Third, the...
