title = "Measurement of the B 0 s → μ + μ − decay properties and search for the B 0 → μ + μ − and B 0 s → μ + μ − γ decays",
abstract = "An improved measurement of the decay Bs0→μ+μ- and searches for the decays B0→μ+μ- and Bs0→μ+μ-γ are performed at the LHCb experiment using data collected in proton-proton collisions at s=7, 8 and 13 TeV, corresponding to integrated luminosities of 1, 2 and 6 fb-1, respectively. The Bs0→μ+μ- branching fraction and effective lifetime are measured to be B(Bs0→μ+μ-)=(3.09-0.43-0.11+0.46+0.15)×10-9 and τ(Bs0→μ+μ-)=(2.07±0.29±0.03) ps, respectively, where the uncertainties include both statistical and systematic contributions. No significant signal for B0→μ+μ- and Bs0→μ+μ-γ decays is found and the upper limits B(B0→μ+μ-)<2.6×10-10 and B(Bs0→μ+μ-γ)[removed]4.9 GeV/c2. Additionally, the ratio between the B0→μ+μ- and Bs0→μ+μ- branching fractions is measured to be Rμ+μ-[removed]",
