Search for Bs0?µ⁺µ^- and B0?µ⁺µ^- decays in pp collisions at vs=7TeV

Abstract: A search for the rare decays B0s??+?? and B0??+?? is performed in pp collisions at ?s=7??TeV, with a data sample corresponding to an integrated luminosity of 1.14??fb?1, 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(B0s??+??)<1.9×10?8 and B(B0??+??)<4.6×10?9, at 95% confidence level.
