An angular analysis of the decay B^0_d → K^*μ^+μ^- is presented, based on proton-proton collision data recorded by the ATLAS experiment at the LHC. The study is using 20.3 fb^-1 of integrated luminosity collected during 2012 at centre-of-mass energy of √(s)=8 TeV. Measurements of the K^* longitudinal polarisation fraction and a set of angular parameters obtained for this decay are presented. The results are compatible with the Standard Model predictions.
