Query: Measurement of electroweak production of a W boson and two forward jets
  in proton-proton collisions at sqrt(s) = 8 TeV   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 8 TeV. The data set was collected with
the CMS detector and corresponds to an integrated luminosity of 19.3 inverse
femtobarns. The measured fiducial cross section for W bosons decaying to
electrons or muons and for pT(j1) > 60 GeV, pT(j2) > 50 GeV, |eta(j)| < 4.7,
and m(jj) > 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 cross section measurement for this
process.
