Abstract

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (p_T) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (H_T), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb⁻¹. The measured cross sections are compared to predictions from Monte Carlo generators, MADGRAPH + PYTHIA and SHERPA, and to next-to-leading-order calculations from BLACKHAT + SHERPA. The differential cross sections are found to be in agreement with the predictions, apart from the p_T distributions of the leading jets at high p_T values, the distributions of the H_T at high-H_T and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.
