Description
A measurement of electroweak-induced production of Wγ and two jets
is performed, where the W boson decays leptonically. The data used in
the analysis correspond to an integrated luminosity of 19.7
fb-1 collected by the CMS experiment in √{s}=8 TeV
proton-proton collisions produced at the LHC. Candidate events are
selected with exactly one muon or electron, missing transverse momentum,
one photon, and two jets with large rapidity separation. An excess over
the hypothesis of the standard model without electroweak production of
Wγ with two jets is observed with a significance of 2.7 standard
deviations. The cross section measured in the fiducial region is 10 .8
± 4 .1(stat) ± 3 .4(syst) ± 0 .3(lumi) fb, which is
consistent with the standard model electroweak prediction. The total
cross section for Wγ in association with two jets in the same
fiducial region is measured to be 23 .2 ± 4 .3(stat) ± 1
.7(syst) ± 0 .6(lumi) fb, which is consistent with the standard
model prediction from the combination of electroweak and quantum
chromodynamics-induced processes. No deviations are observed from the
standard model predictions and experimental limits on anomalous quartic
gauge couplings f M,0-7 /Λ4, f
T,0-2 /Λ4, and f T,5-7
/Λ4 are set at 95% confidence level. [Figure not
