Differential branching fraction and angular analysis of the $B^{0} \to K^{*0} \mu^{+}\mu^{-}$ decay
The angular distribution and differential branching fraction of the $B^{0} \to K^{*0} \mu^{+}\mu^{-}$ decay are studied as a function of dimuon invariant mass squared, $q^{2}$, using a data sample with an integrated luminosity of 1 fb$^{-1}$. A first measurement of the zero-crossing point of the fo...

| description | The angular distribution and differential branching fraction of the $B^{0} \to K^{*0} \mu^{+}\mu^{-}$ decay are studied as a function of dimuon invariant mass squared, $q^{2}$, using a data sample with an integrated luminosity of 1 fb$^{-1}$. A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system of $q_{0}^{2}$ = (4.9$^{+1.1}_{-1.3}$) GeV$^2/c^{4}$ is presented. Results are in good agreement with Standard Model predictions. |
