W+n-jet predictions at the Large Hadron Collider at next-to-leading   order matched with a parton shower
  For the first time, differential cross sections for the production of W-bosons in conjunction with up to three jets, computed at next-to leading order in QCD and including parton shower corrections, are presented and compared to recent experimental data from the Large Hadron Collider.
