Measurement of form-factor-independent observables in the decay $B^{0} \to K^{*0} \mu^+ \mu^-$

Abstract : We present a measurement of form-factor independent angular observables in the decay \mbox{$B^0\to K^{*}(892)^{0}\mu^+ \mu^-$}. The analysis is based on a data sample corresponding to an integrated luminosity of 1.0fb$^{-1}$, collected by the LHCb experiment in $pp$ collisions at a center-of-mass energy of 7TeV. Four observables are measured in six bins of the dimuon invariant mass squared, $q^2$, in the range $0.1
