Angular analysis of the $B^{0} \rightarrow K^{*0} \mu^{+} \mu^{-}$ decay An angular analysis of the $B^{0}\rightarrow K^{*0}\mu^{+}\mu^{-}$ decay is presented using $pp$-collision data collected at the LHCb experiment. The dataset corresponds to an integrated luminosity of 3 fb$^{-1}$. The analysis uses the full angular distribution and measures all $CP$-averaged angular observables and the correlations between these observables, taking into account the contamination from $K^{+}\pi^{-}$ in an S-wave configuration. Neglecting the correlations between the observables, the measurements are largely in agreement with the Standard Model predictions. However, the observable $P'_{5}$ exhibits a local tension with respect to the Standard Model prediction at a level of 3.7$\sigma$. eng flavour physics; B physics; rare decay; 2015
