Book excerpt: We present a measurement of the absolute branching fraction for D° → K−? using the reconstruction of the decay chain {bar B} → D*+Xl−{bar {nu}}, D*+ → D°?+ 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 Br(D° → K−?+) = [3.81 ± 0.15(stat.) ± 0.16(syst.)]%.
