Angular Analysis of $B\rightarrow K^{*} \mu \mu$ with the ATLAS Experiment

A measurement of the muon forward-backward asymmetry $A_{fb}$ and the fraction of the K* longitudinal polarisation $F_{L}$ in the decay $B\rightarrow K^{*} \mu \mu$ is presented. The data used was collected with the ATLAS detector at the Large Hadron Collider in proton-proton collisions at a centre of mass energy of $\sqrt{s} = 7\,\text{TeV}$ in the year 2011 and amounts to 4.9$fb^{-1}$ of integrated luminosity. The measurement is compared to the predictions of the Standard Model and the results of other experiments.
