Abstract: We present a measurement of the electroweak production cross section of a W boson in association with two jets events in pp collisions at $\sqrt{s} =$ 8 TeV. The analyzed dataset corresponds to an integrated luminosity of 19.3 fb $^{-1}$ collected by the CMS detector at the LHC. The measured value of the cross section in the fiducial region for electroweak production of W (W $\to\ell\nu$ , with $\ell={\mathrm{e}},{{\mu}}$ )+2 jets is 0.42 $\pm$ 0.04 (stat.) $\pm$ 0.09 (syst.) $\pm$ 0.01 (lumi.) pb, which is consistent with the standard model prediction of 0.50 $\pm$ 0.02 (scale) $\pm$ 0.02 (PDF) pb obtained by MADGRAPH interfaced to PYTHIA 6.
