Measurement of branching fractions and CP-violating charge asymmetries for B-meson decays to D-(*)(D)over-bar((*)), and implications for the Cabibbo-Kobayashi-Maskawa angle gamma

Abstract:

We present measurements of the branching fractions and charge asymmetries of B decays to all D(*)D̄(*) modes. Using 232×106 BB̄ pairs recorded on the Υ(4S) resonance by the BABAR detector at the e+e- asymmetric B factory PEP-II at the Stanford Linear Accelerator Center, we measure the branching fractions B(B0→D*+D*-)=(8.1±0. 6±1.0)×10-4, B(B0→D*±D)=(5.7±0.7±0. 7)×10-4, B(B0→D+D-)=(2.8±0.4±0.5)×10-4, B(B+→D*+D̄*0)=(8.1±1.2±1.2)×10-4, B(B+→D*+D̄0)=(3.6±0.5±0.4)×10-4, B(B+→D+D̄*0)=(6.3±1.4±1.0)×...
