Abstract

The determination of the differential branching fraction and the first angular analysis of the decay B s0rarr phimu+mu- are presented using data, corresponding to an integrated luminosity of 1.0 fb -1, collected by the LHCb experiment at radics = 7TeV. The differential branching fraction is determined in bins of q2, the invariant dimuon mass squared. Integration over the full q2 range yields a total branching fraction of B(B s0rarr phimu+mu-) = (7.07 -0.59+0.64) times 10 -7, where the first uncertainty is statistical, the second systematic, and the third originates from the branching fraction of the normalisation channel. An angular analysis is performed to determine the angular observables FL, S3, A6, and A9. The observables are consistent with Standard Model expectations.
