This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors report on a search for B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -} and B{sub d}{sup 0} {yields} {mu}{sup +}{mu}{sup -} decays in p{bar p} collisions at {radical}s = 1.96 TeV using 171 pb{sup -1} of data collected by the CDF II experiment at the Fermilab Tevatron Collider. The decay rates of these rare processes are sensitive to contributions from physics beyond the Standard Model. One event survives all the selection requirements, consistent with the background expectation. They derive branching ratio limits of {Beta}(B{sub s}{sup 0} {yields} {mu}{sup +}{mu}{sup -})

Download or read book Search for $B_{s, D} \rightarrow \mu^+\mu^-$ Decays with 10/fb of $p\overline{p}$ Collisions written by and published by . This book was released on 2013 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: A search for the rare decays of B$^0$$_s$→ [mu]+ [mu]- and B$^0$$_d$ → + [mu]+ [mu]- is presented in p$\bar{p}$ collisions at √s=1.96 TeV corresponding to 10 fb-1 of integrated luminosity collected by the CDF II detector. The observed number of B$^0$$_d$ candidates is consistent with background-only expectations and yields an upper limit on the branching fraction B(B$^0$$_d$ → [mu]+ [mu]-) of 4.2 x 10-9 at 95% confidence level. An excess is observed for the B0s signal region. The probability that background processes alone could produce such an excess or larger is 0.94%. The probability that the combination of background and the expected standard model rate B$^0$$_s$ → [mu]+ [mu]- could produce such an excess or larger is 6.8%. These data are used to determine a central value of B(B$^0$$_s$ → [mu]+ [mu]-) = (1:3+0.9 -0.7) 10-8 as well as a two sided limit at 90% C.L. of 2:2 10-9

Available in PDF, EPUB and Kindle. Book excerpt: A search for the rare decays B(s) to dimuons and B0 to dimuons is performed in pp collisions at sqrt(s)=7 TeV, with a data sample corresponding to an integrated luminosity of 1.14 inverse femtobarns, collected by the CMS experiment at the LHC. In both cases, the number of events observed after all selection requirements is consistent with expectations from background and standard-model signal predictions. The resulting upper limits on the branching fractions are B(B(s) to mu+̂ mu-̂)

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The authors search for b → s??− transitions in B meson (B+, B°, or B{sub s}°) decays with 924 pb−1 of p{bar p} collisions at √s = 1.96 TeV collected with the CDF II detector at the Fermilab Tevatron. They find excesses with significances of 4.5, 2.9, and 2.4 standard deviations in the B+ →?+?−K+, B° →?+?−K*(892)°, and B{sub s}° →?+?−? decay modes, respectively. Using B → J/?h (h - K+, K*(892)°,?) decays as normalization channels, they report branching fractions for the previously observed B+ and B° decays as normalization channels, they report branching fractions for the previously observed B+ and B° decays,?(B+ →?+?−K+) = (0.59 ± 0.15 ± 0.04) x 10−6, and?(B° →?+?−K*(892)°) = (0.81 ± 0.30 ± 0.10) x 10−6, where the first uncertainty is statistical, and the second is systematic. These measurements are consistent with the world average results, and are competitive with the best available measurements. They set an upper limit on the relative branching fraction?(B{sub s}°→?+?−?)/?(B{sub s}°→J/??)
