| Abstract: The angular distributions and the differential branching fraction of the decay$\text{B}^{0} \rightarrow \text{K}^{*0} \mu^{+} \mu^{-}$ are studied using an integrated luminosity of 5.2~\fbinv of data collected with the CMS detector. The forward-backward asymmetry of the muons $A_{FB}$, the $\text{K}^{\ast 0}$ longitudinal polarization fraction $F_{L}$, and the differential branching fraction ${\rm d}\mathcal{B}/{\rm d}q^{2}$, are determined as a function of the dimuon invariant mass squared. The measurements are in good agreement with the standard model. | ||
