Angular analysis and differential branching fraction of the decay B {/s 0} → ϕμ + μ -
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...

| Sumario: | 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. |
