Measurement of the Differential Cross Section of W-Bosons Produced in Association with Jets in $pp$ collisions at $\sqrt{s} = 7$ TeV

We present measurements of the cross-section for the production of W+jets, where the W decays to produce a muon, as a function of several variables, including the transverse momenta and pseudorapidity of the four leading jets, the scalar sum of jet transverse momenta, and the difference in azimuthal angle between each jet and the muon. The data sample corresponds to 5.0 inverse femtobarns of pp collisions at a center-of-mass energy of 7 TeV, collected with the CMS detector at the LHC. The measured cross-sections are compared to predictions from Monte Carlo generators, MadGraph+Pythia and Sherpa, and to NLO calculations from BlackHat+Sherpa.
