The ${\bar{B}}_d\to {\bar{K}}^{\ast 0}{\mu }^{+}{\mu }^{-}$ decay

In this paper the potential for the discovery of new physics in the exclusive decay ${\bar{B}}_d\to {\bar{K}}^{\ast 0}{\mu }^{+}{\mu }^{-}$ is discussed. Attention is paid to constructing observables which are protected from uncertainties in QCD form factors and at the same time observe the symmetries of the angular distribution. We discuss the sensitivity to new physics in the observables including the effect of CP-violating phases.
