Available in PDF, EPUB and Kindle. Book excerpt: The authors search for B° meson decays into two-body combinations of K°, [eta], [eta]', and [phi] mesons in 324 million B{bar B} pairs collected with the BABAR detector at the PEP-II asymmetric-energy ee− collider at SLAC. They measure the following branching fractions (upper limits at 90% confidence level) in units of 10−6: [Beta](B° 2![eta]K°) = 1.8{sub -0.6}{sup +0.7} ± 0.1 (
Download or read book Search for the Decay B0 Eta Phi at the BABAR Experiment written by and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented is a search for the rare hadronic B meson decay B0 -> eta phi. It is based on 86 x 10^6 BB pairs recorded by the BABAR experiment at the Stanford Linear Accelerator Center between 1999 and 2002. phi mesons are reconstructed in the channel phi -> K+ K-. eta mesons are reconstructed in the channels eta -> gamma gamma and eta -> pi+ pi- pi0. Signal events are identified by a candidate counting and a maximum-likelihood method. To ensure an unbiased measurement, the number of signal events is blinded throughout the analysis. Although no significant signal is found by either method, the maximum-likelihood method obtains a smaller statistical uncertainty. In this method, the branching fraction of the decay B0 -> eta phi is determined by the upper limit BR (B0 -> eta phi)

Book excerpt: We study the decays B[sup +] [yields] [eta][sub c]K[sup +] and B[sup 0] [yields] [eta][sub c]K[sup 0], where the [eta][sub c] is reconstructed in the K[sub S][sup 0] K[sup [+-]] [pi][sup [-+]] and K[sup +]K[sup -] [pi][sup 0] decay modes. Results are based on a sample of 86 million B[bar B] pairs collected with the BABAR detector at the SLAC e[sup +]e[sup -] B Factory. We measure the branching fractions [Beta](B[sup +] [yields] [eta][sub c]K[sup +]) = (1.34 [+-] 0.09 [+-] 0.13 [+-] 0.41) x 10[sup -3] and [Beta](B[sup 0] [yields] [eta][sub c]K[sup 0]) = (1.18 [+-] 0.16 [+-] 0.13 [+-] 0.37) x 10[sup -3], where the first error is statistical, the second is systematic, and the third reflects the [eta][sub c] branching fraction uncertainty. In addition, we search for B [yields] [eta][sub c]K events with [eta][sub c] [yields] 2(K[sup +]K[sup -]) and [eta][sub c] [yields] [phi][phi] and determine the [eta][sub c] decay branching fraction ratios [Beta]([eta][sub c] [yields] 2(K[sup +]K[sup -]))/[Beta]([eta][sub c] [yields] K[bar K][pi]) = (2.3 [+-] 0.7 [+-] 0.6) x 10[sup -2] and [Beta]([eta][sub c] [yields] [phi][phi])/[Beta]([eta][sub c] [yields] K[bar K][pi]) = (5.5 [+-] 1.4 [+-] 0.5) x 10[sup -2].
