Available in PDF, EPUB and Kindle. Book excerpt: The authors measure the absolute branching fraction for D° → K−? using partial reconstruction of {bar B}° → D*+Xl−{bar {nu}}{sub {ell}} decays, in which only the charged lepton and the pion from the decay D*+ → D°?+ are used. Based on a data sample of 230 million B{bar B} pairs collected at the?(4S) resonance with the BABAR detector at the PEP-II asymmetric-energy B Factory at SLAC, they obtain?(D° → K−?+) = (4.007 ± 0.037 ± 0.070)%, where the first error is statistical and the second error is systematic.
