Abstract:
A combination of results on the rare decays Bs0μ+μB^0_s \to \mu^+\mu^- and B0μ+μB^0 \to \mu^+\mu^- from the CMS and LHCb experiments is performed. After accounting for known correlations, the average time-integrated branching fraction of the decay Bs0μ+μB^0_s \to \mu^+\mu^- is determined to be B(Bs0μ+μ)=(2.9±0.7)×109{\cal B}(B^0_{s} \to \mu^+\mu^-) = (2.9 \pm 0.7) \times 10^{-9} where the uncertainties include both statistical and systematic sources.
