Download or read book Search for Rare Quark Annihilation Decays B u2192 D atop s written by and published by . This book was released on 2006 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report on a search for the decay B± → D$(*)±top{s}$? using 212.2 fb-1 of data collected with the BABAR detector at the PEP-II B Factory at the Stanford Linear Accelerator Center between 1999 and 2004. This sample of 234 x 106 e+e- → Y(4S) → B$ar{B}$ events yields no significant signal. They report the Bayesian upper limits ?(B± → D$(*)±top{s}$?) x ?(D$(*)±top{s}$ → ??±) 8.6 x 10sup-8/sup and ?(Bsup±/sup → D$(*)±top{s}$sup±/sup?) x ?(Dsubs/subsup±/sup → ??sup±/sup) 5.4 x 10sup-7/sup at the 90% C.L. Using the latest measurement of ?(D$(*)±top{s}$ → ??sup±/sup), they report: ?(Bsup±/sup → Dsubs/subsup±/sup?) 1.8 x 10sup-6/sup and ?(Bsup±/sup → D*subs/subsup±

Book excerpt: We report on searches for B− → D{sub s}− ? and B− → D*{sub s}− ?. In the context of the Standard Model, these decays are expected to be highly suppressed since they proceed through annihilation of the b and {bar u} quarks in the B− meson. Our results are based on 234 million ?(4S) → B{bar B} decays collected with the BABAR detector at SLAC. We find no evidence for these decays, and we set Bayesian 90% confidence level upper limits on the branching fractions ?(B− → D{sub s}−?)
