An angular analysis and a measurement of the differential branching fraction of the decay B 0 s + -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 3 below the Standard Model predictions.
