EW Wgamma plus 2 jets at 13 TeV full run 2

A measurement is presented for the electroweak production of a W boson, a photon ($\gamma$), and two jets (j) in proton-proton collisions. The leptonic decay of W boson is selected by requiring one identified electron or muon and a large missing transverse momentum. The two jets are required to have...

description A measurement is presented for the electroweak production of a W boson, a photon ($\gamma$), and two jets (j) in proton-proton collisions. The leptonic decay of W boson is selected by requiring one identified electron or muon and a large missing transverse momentum. The two jets are required to have a high dijet mass and a large separation in pseudorapidity. The measurement is performed with the data collected by the CMS detector at a center-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 138 $~\mathrm{fb}^{-1}$. The cross section for the electroweak W$\gamma$jj production in a restricted fiducial region is $19.2\pm 4.0~\mathrm{fb}$, while the inclusive cross section for W$\gamma$jj production in the same fiducial region is $90\pm 11~\mathrm{fb}$. Differential cross sections are also measured with the distributions unfolded to the parton level. Constraints are placed on anomalous quartic gauge couplings in terms of dimension-8 effective field theory operators. All results are in agreement with standard model expectations.
