Abstract

An angular analysis of the decay B_d⁰ → 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.[Figure not available: see fulltext.].
