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 -})

Available in PDF, EPUB and Kindle. Book excerpt: We report on a search for B0s → ?+ ?- and B0d → mu+mu- decays in p anti-p collisions at √s = 1.96 TeV using 364.4 pb -1 of data collected by the CDF II dectector at Fermilab Tevatron Collider. After applying all selection requirements, we observe no candidates inside the B0s or B0d mass windows. The resulting upper limits on the branching fractions are ?(B0s → ?+?-) 1.5 x 10sup-7/sup and ?(B0subd/sub → ?+?-) 3.9 x 10
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-̂)
