Abstract
A search for the rare decays B[subscript s][superscript 0]→μ[superscript +]μ[superscript -] and B[superscript 0]→μ[superscript +]μ[superscript - ] is performed in pp collisions at √s=7 TeV, with a data sample corresponding to an integrated luminosity of 1.14 fb[superscript -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(B[subscript s][superscipt 0]→μ[superscript +]μ[superscript -])<1.9×10[superscript -8] and B(B[superscript 0]→μ[superscript +]μ[superscript -])<4.6×10[superscript -9], at 95% confidence level.
