We present measurements of the branching fractions and charge asymmetries of B decays to all D* anti-D* modes. Using 232x10^(6) B anti-B pairs recorded on the Upsilon(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)x10(-4), B(B0 ->(D*+- D-+)=(5.7 +/- 0.7 +/- 0.7)x10^(-4), B(B0 -> D+D-)=(2.8 +/- 0.4 +/- 0.5)x10^(-4), B(B+ -> D*+ anti-D*0)=(8.1 +/- 1.2 +/- 1.2)x10^(-4), B(B+ -> D*+ anti-D0)=(3.6 +/- 0.5 +/- 0.4)x10^(-4), B(B+ -> D+ anti-D*0)=(6.3 +/- 1.4 +/- 1.0)x10^(-4), and B(B+ -> D+ anti-D0)=(3.8 +/- 0.6 +/- 0.5)x10^(-4), where in each case the first uncertainty is statistical and the second systematic. We also determine the limits B(B0 -> D*0 anti-D*0)< 0.9x10^(-4), B(B0 -> D*0 anti-D0)< 2.9x10^(-4), and B(B0 -> D0 anti-D0)< 0.6x10(-4), each at 90% confidence level. All decays above denote either member of a charge-conjugate pair. We also determine the CP-violating charge asymmetries A(B0 -> D*+/- D-+)=0.03 +/- 0.10 +/- 0.02, A(B+ -> D*+ anti-D*0)=-0.15 +/- 0.11 +/- 0.02, A(B+ -> D*+ anti-D0)=-0.06 +/- 0.13 +/- 0.02, A(B+ -> D+ anti-D*0)=0.13 +/- 0.18 +/- 0.04, and A(B+ -> D+ anti-D0)=-0.13 +/- 0.14 +/- 0.02. Additionally, when we combine these results with information from time-dependent CP asymmetries in B0 -> D*+ D*- decays and world-averaged branching fractions of B decays to Ds* anti-D* modes, we find the Cabibbo-Kobayashi-Maskawa phase gamma is favored to lie in the range (0.07-2.77) radians (with a +0 or +pi radians ambiguity) at 68% confidence level.

Abstract

We present measurements of the branching fractions and charge asymmetries of B decays to all D* anti-D* modes. Using 232x10^(6) B anti-B pairs recorded on the Upsilon(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)x10(-4), B(B0 ->(D*+- D-+)=(5.7 +/- 0.7 +/- 0.7)x10^(-4), B(B0 -> D+D-)=(2.8 +/- 0.4 +/- 0.5)x10^(-4), B(B+ -> D*+ anti-D*0)=(8.1 +/- 1.2 +/- 1.2)x10^(-4), B(B+ -> D*+ anti-D0)=(3.6 +/- 0.5 +/- 0.4)x10^(-4), B(B+ -> D+ anti-D*0)=(6.3 +/- 1.4 +/- 1.0)x10^(-4), and B(B+ -> D+ anti-D0)=(3.8 +/- 0.6 +/- 0.5)x10^(-4), where in each case the first uncertainty is statistical and the second systematic. We also determine the limits B(B0 -> D*0 anti-D*0)< 0.9x10^(-4), B(B0 -> D*0 anti-D0)< 2.9x10^(-4), and B(B0 -> D0 anti-D0)< 0.6x10(-4), each at 90% confidence level. All decays above denote either member of a charge-conjugate pair. We also determine the CP-violating charge asymmetries A(B0 -> D*+/- D-+)=0.03 +/- 0.10 +/- 0.02, A(B+ -> D*+ anti-D*0)=-0.15 +/- 0.11 +/- 0.02, A(B+ -> D*+ anti-D0)=-0.06 +/- 0.13 +/- 0.02, A(B+ -> D+ anti-D*0)=0.13 +/- 0.18 +/- 0.04, and A(B+ -> D+ anti-D0)=-0.13 +/- 0.14 +/- 0.02. Additionally, when we combine these results with information from time-dependent CP asymmetries in B0 -> D*+ D*- decays and world-averaged branching fractions of B decays to Ds* anti-D* modes, we find the Cabibbo-Kobayashi-Maskawa phase gamma is favored to lie in the range (0.07-2.77) radians (with a +0 or +pi radians ambiguity) at 68% confidence level.
