 Combination of the ATLAS, CMS and LHCb results on the $B^0_{(s)} \to \mu^+\mu^-$ decays /CMS Collaboration ; LHCb Collaboration ; ATLAS Collaboration A combination of results on the rare $B^0_s \to \mu^+\mu^-$ and $B^0 \to \mu^+\mu^-$ decays from the ATLAS, CMS, and LHCb experiments using data collected at the Large Hadron Collider between 2011 and 2016, is presented. The $B^0_s \to \mu^+\mu^-$ branching fraction is obtained to be $(2.69\,^{+\, 0.37}_{-\, 0.35}) \times 10^{-9}$ and the effective lifetime of the $B^0_s \to \mu^+\mu^-$ decay is measured to be $\tau_{B^0_s \to \mu^+\mu^-} = 1.91^{+0.37}_{-0.35}$ ps.
