Abstract

An angular analysis of the rare decay B⁰_s→ϕμ⁺μ^- is presented, using proton-proton collision data collected by the LHCb experiment at centre-of-mass energies of 7, 8 and 13~\rmTeV, corresponding to an integrated luminosity of 8.4~\rmfb^-1. The observables describing the angular distributions of the decay B⁰_s→ϕμ⁺μ^- are determined in regions of q², the square of the dimuon invariant mass. The results are consistent with Standard Model predictions.
