Summary: | A measurement is presented of electroweak (EW) production of a
boson in association with two jets in proton-proton collisions at
. The data sample was recorded by the CMS Collaboration at the LHC and corresponds to an integrated luminosity of 35.9
. The measurement is performed for the
jj final state (with
indicating a lepton-neutrino pair, and j representing the quarks produced in the hard interaction) in a kinematic region defined by invariant mass
and transverse momenta
. The cross section of the process is measured in the electron and muon channels yielding
per channel, in agreement with leading-order standard model predictions. The additional hadronic activity of events in a signal-enriched region is studied, and the measurements are compared with predictions. The final state is also used to perform a search for anomalous trilinear gauge couplings. Limits on anomalous trilinear gauge couplings associated with dimension-six operators are given in the framework of an effective field theory. The corresponding 95% confidence level intervals are
,
, and
. These results are combined with the CMS EW
analysis, yielding the constraint on the
coupling:
