A measurement is presented of the cross section for the electroweak production of a W boson in association with two jets in proton-proton collisions at a center-of-mass energy of 8TeV. The data set was collected with the CMS detector and corresponds toan integrated luminosity of 19.3 fb-1. The measured fiducial cross section for W bosons decaying to electrons or muons and for pTj1 > 60 GeV, pTj2 > 50 GeV, |ηj| < 4.7, and mjj > 1000 GeV is 0.42±0.04 (stat) ±0.09 (syst) ±0.01 (lumi) pb. This result is consistent with the standard model leading-order prediction of 0.50 ±0.02 (scale) ± 0.02 (PDF) pb obtained with MadGraph5_amc@nlo 2.1 interfaced to pythia 6.4. This is the first crosssection measurement for this process.
