Angular analysis of $B_d^0\to K^{\ast }{\mu }^{+}{\mu }^{-}$ decays in $pp$ collisions at $\sqrt{s}=8$ TeV with the ATLAS detector

Abstract

An angular analysis of the decay $B_d^0\to K^{\ast }{\mu }^{+}{\mu }^{-}$ 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 $\sqrt{s}=8$ TeV. Measurements of the $K^{\ast }$ longitudinal polarisation fraction and a set of angular parameters obtained for this decay are presented. The results are compatible with the Standard Model predictions.
