Measurement of the Branching Fraction and Polarization for the Decay B[superscript -]→D[superscript *0]K[superscript *-]
We present a study of the decay B[superscript -]→D[superscript *0]K[superscript *-] based on a sample of 86×10[superscript 6] Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure the branching fraction B(B[superscript -]→D[superscript *0]K[...

Summary: | We present a study of the decay B[superscript -]→D[superscript *0]K[superscript *-] based on a sample of 86×10[superscript 6] Υ(4S)→BB̅ decays collected with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC. We measure the branching fraction B(B[superscript -]→D[superscript *0]K[superscript *-])=(8.3±1.1(stat)±1.0(syst))×10[superscript -4], and the fraction of longitudinal polarization in this decay to be Γ[subscript L]/Γ=0.86±0.06(stat)±0.03(syst). |
