Measurement of BD0 → K- π+using partial reconstruction of B̄ → D*+Xl-ν̄

Abstract:
We present a measurement of the absolute branching fraction for D0 → K-π+ using the reconstruction of the decay chain B̄ → D*+Xl-ν̄, D0π+where only the lepton and the low-momentum pion from the D*+ are detected. With data collected by the CLEO II detector at the Cornell Electron Storage Ring, we have determined B(D0 → K- π+ = [3.81 ± 0.15(stat) ± 0.16(syst)]%.
