Description:
  'Rapidity distributions are presented for events containing either a
  $Z$ boson or a photon in association with a single jet in proton-proton
  collisions produced at the CERN LHC. The data, collected with the CMS
  detector at $\sqrt{s} = 7$ TeV, correspond to an integrated luminosity of 5.0/fb.
  The individual rapidity distributions of the boson and the jet are
  consistent within 5\% with expectations from perturbative QCD. However,
  QCD predictions for the sum and the difference in rapidities of the two
  final-state objects show significant discrepancies with CMS data. In
  particular, next-to-leading-order QCD calculations, and two Monte Carlo
  event generators using different methods to merge matrix-element
  partons with evolved parton showers, appear inconsistent with the data
  as well as with each other.'
