Abstract
An angular analysis and a measurement of the differential branching fraction of the decay B s → 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 q 2, 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 < q 2< 6 GeV 2/c 4, where precise theoretical calculations are available, the differential branching fraction is found to be more than 3σ below the Standard Model predictions.
