英文摘要	Differential cross sections for a w boson produced in association with jets are measured in a data sample of proton-proton collisions at a center-of-mass energy of 8 tev recorded with the cms detector and corresponding to an integrated luminosity of 19.6 fb(-1). the w bosons are identified through their decay mode w ->mu nu. the cross sections are reported as functions of jet multiplicity, transverse momenta, and the scalar sum of jet transverse momenta ( h-t) for different jet multiplicities. distributions of the angular correlations between the jets and the muon are examined, as well as the average number of jets as a function of h-t and as a function of angular variables. the measured differential cross sections are compared with tree-level and higher-order recent event generators, as well as next-to-leading-order and next-to-nextto-leading-order theoretical predictions. the agreement of the generators with the measurements builds confidence in their use for the simulation of w+ jets background processes in searches for new physics at the lhc.
