(ProQuest: ... denotes formulae and/or non-USASCII text omitted; see image).The angular distribution and differential branching fraction of the decay B super(0) arrow right K super(0) mu super(+) mu super(-) are studied using a data sample, collected by the LHCb experiment in pp collisions at ... TeV, corresponding to an integrated luminosity of 1.0 fb super(-1). Several angular observables are measured in bins of the dimuon invariant mass squared, q super(2). A first measurement of the zero-crossing point of the forward-backward asymmetry of the dimuon system is also presented. The zero-crossing point is measured to be ..., where the uncertainty is the sum of statistical and systematic uncertainties. The results are consistent with the Standard Model predictions.
