Angular Analysis of $B_{d}^{0} \to K^{\star0}\mu^{+}\mu^{-}$ Decays at ATLAS

The large amount of Heavy Flavour data collected by the ATLAS experiment allow to analyze rare processes potentially sensitive to New Physics, which could be evident in processes that are naturally suppressed in the Standard Model. The results of the analysis of the angular distribution parameters describing the decay $B_{d}^{0} \to K^{\star0}\mu^{+}\mu^{-} \to K^{+}\pi^{-}\mu^{+}\mu^{-}$ based on full Run 1 data are presented. They are consistent with the Standard Model predictions.
