English AbstractThe cross-section for the production of two jets in association with a leptonically decaying z boson (zjj) is measured in proton-proton collisions at a centre-of-mass energy of 13 tev, using data recorded with the atlas detector at the large hadron collider, corresponding to an integrated luminosity of 3.2 fb(-1). the electroweak zjj cross-section is extracted in a fiducial region chosen to enhance the electroweak contribution relative to the dominant drell-yan zjj process, which is constrained using a data-driven approach. the measured fiducial electroweak cross-section is sigma(zjj)(ew) = 119 +/- 16 (stat.) +/- 20 (syst.) +/- 2 (lumi.) fb for dijet invariant mass greater than 250 gev, and 34.2 +/- 5.8 (stat.) +/- 5.5 (syst.) +/- 0.7 (lumi.) fb for dijet invariant mass greater than 1 tev. standard model predictions are in agreement with the measurements. the inclusive zjj cross-section is also measured in six different fiducial regions with varying contributions from electroweak and drell-yan zjj production.
