Summary: | A measurement of the electroweak (EW) production of two jets in association with a Z boson in protonproton collisions at √s = 13 TeV is presented, based on
data recorded in 2016 by the CMS experiment at the LHC
corresponding to an integrated luminosity of 35.9 fb–1. The
measurement is performed in the jj final state with including electrons and muons, and the jets j corresponding to the
quarks produced in the hard interaction. The measured cross
section in a kinematic region defined by invariant masses
m > 50 GeV, mjj > 120 GeV, and transverse momenta
pTj > 25 GeV is σEW(jj) = 534 ± 20 (stat) ± 57 (syst) fb,
in agreement with leading-order standard model predictions. The final state is also used to perform a search
for anomalous trilinear gauge couplings. No evidence is
found and 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 −2.6 < cWWW /Λ2 <
2.6 TeV−2 and −8.4 < cW /Λ2 < 10.1 TeV−2. The additional jet activity of events in a signal-enriched region is
also studied, and the measurements are in agreement with
predictions. |
