Download or read book Search for Rare Quark-Annihilation Decays, Charged B Mesons Decaying to Charged D(S) Mesons And Phi Mesons written by and published by . This book was released on 2008 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report on a search for the decay B{sup {+-}} 2!D{sub s}{sup (*){+-}} [phi] 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 ee− 2 2!B{bar B} events yields no significant signal. They report the Bayesian upper limits [Beta](B{sup {+-}} 2!D{sub s}{sup {+-}} [phi]) x [Beta](D{sub s}{sup {+-}} 2![phi][pi]{sup {+-}})
