Abstract
An angular analysis and a measurement of the differential branching fraction
of the decay B0
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 < q2 < 6 GeV2/c4
, where precise theoretical calculations are available,
the differential branching fraction is found to be more than 3 σ below the Standard
Model predictions.
