Abstract
An angular analysis and a measurement of the differential branching fraction of the decay Bs0 → ϕμ+μ− are presented, using data corresponding to an integrated luminosity of 3.0 fb−1 of pp collisions recorded by the LHCb experiment at s=7 and 8 TeV. Measurements are reported as a function of q2, the square of the dimuon invariant mass and results of the angular analysis are found to be consistent with the Standard Model. In the range 1 < q2< 6 GeV2/c4, where precise theoretical calculations are available, the differential branching fraction is found to be more than 3σ below the Standard Model predictions.
