Abstract

An angular analysis of the decay B0d → 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 = 8TeV. 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.
