Abstract
We present a measurement of form-factor-independent angular observables in the decay ${B}^{0}\ensuremath{\rightarrow}{K}^{*}(892{)}^{0}{\ensuremath{\mu}}^{+}{\ensuremath{\mu}}^{\ensuremath{-}}$. The analysis is based on a data sample corresponding to an integrated luminosity of $1.0\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$, collected by the LHCb experiment in $pp$ collisions at a center-of-mass energy of 7 TeV. Four observables are measured in six bins of the dimuon invariant mass squared ${q}^{2}$ in the range $0.1<{q}^{2}<19.0\text{ }\text{ }{\mathrm{GeV}}^{2}/{c}^{4}$. Agreement with recent theoretical predictions of the standard model is found for 23 of the 24 measurements. A local…
