Description
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 →μ ν . The
cross sections are reported as functions of jet multiplicity, transverse
momenta, and the scalar sum of jet transverse momenta (HT )
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 HT 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-next-to-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.
