Angular analysis of the rare decay B0s → ϕμ+μ−

Abstract

An angular analysis of the rare decay B0 s → φµ+µ − is presented, using protonproton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 8.4 fb−1 . The observables describing the angular distributions of the decay B0 s → φµ+µ − are determined in regions of q 2 , the square of the dimuon invariant mass. The results are consistent with Standard Model predictions.
