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

This book was released on 2015 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: The angular distributions and the differential branching fraction of the decay B0→K*(892)0[mu]+[mu]- are studied using data corresponding to an integrated luminosity of 20.5 fb-1 collected with the CMS detector at the LHC in pp collisions at √s = 8 TeV. Additionally, from 1430 signal decays, the forward-backward asymmetry of the muons, the K*(892)0 longitudinal polarization fraction, and the differential branching fraction are determined as a function of the dimuon invariant mass squared. Our measurements are among the most precise to date and are in good agreement with standard model predictions.

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/??)

Book excerpt: "$B sp pm$ mesons are reconstructed through the decay chain $B sp pm to chi sb{c}K sp pm, chi sb{c} to J/ psi gamma,$ and $J/ psi to mu sp+ mu sp-.$ Using data taken at the Collider Detector at Fermilab in $ bar pp$ collisions at $ sqrt{s}$ = 1.8 TeV during the 1988/89 run, we have seen the signal of the $B sp pm$ mesons from this decay channel although the statistics still need to be improved. By Monte Carlo methods, we also conclude that it is possible to resolve the individual $ chi sb{c1}$ and $ chi sb{c2}$ states by making higher photon energy cuts." --
