  "abstract": "A measurement of the electroweak (EW) production of two jets in association with a Z boson in proton-proton collisions at $\\sqrt{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 $\\ell\\ell\\mathrm{jj}$ final state with $\\ell$ 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_{\\ell\\ell} > $ 50 GeV, $m_{\\mathrm{jj}} > $ 120 GeV, and transverse momenta $p_{\\mathrm{T j}} > $ 25 GeV is $\\sigma_\\mathrm{EW}(\\ell\\ell\\mathrm{jj})= $ 552 $\\pm$ 19 (stat) $\\pm$ 55 (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 < c_{WWW}/\\Lambda^2 < 2.6 $ TeV$^{-2}$ and $-8.4 < c_{W}/\\Lambda^2 < 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.",
