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 -})

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.

Here, a study of the decays B0s 2![mu]+[mu]- and B0 2![mu]+[mu]- has been performed using data corresponding to an integrated luminosity of 25 fb-1 of 7 and 8 TeV proton-proton collisions collected with the ATLAS detector during the LHC Run 1. For the B0 dimuon decay, an upper limit on the branching fraction is set at B(B0 2![mu]+[mu]- )

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 thesis presents a measurement of the branching fraction for the exclusive semileptonic decay {bar B}{sup 0} {yields} D*{sup +}{mu}{sup -}{nu}{sub {mu}}. This decay is essentially the decay of a b quark to a c quark inside the meson with the release of a muon and neutrino, and it provides a very clean signal for measuring various B meson decay properties. the data for this measurement consist of 22.3 million B{bar B} pairs collected by the BABAR detector at the Stanford Linear Accelerator Center in 1999-2000. The branching fraction is measured to be {Beta}({bar B}{sup 0} {yields} D*{sup +}{mu}{sup -}{bar {nu}}{sub {mu}}) = [4.72 {+-} 0.10 (data stat.) {+-} 0.06 (MC stat.) {+-} 0.20 (syst.) {+-} 0.17 (other {Beta})]%.
