dc.description.abstract	The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton–proton collisions at s√=8TeVs=8TeV , is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 fb-1fb-1 . The electroweak cross section for the ℓℓjjℓℓjj final state (with ℓ=eℓ=e or μμ and j representing the quarks produced in the hard interaction) in the kinematic region defined by Mℓℓ>50Mℓℓ>50 GeVGeV , Mjj>120Mjj>120 GeVGeV , transverse momentum pTj>25pTj>25 GeVGeV , and pseudorapidity \|ηj\|<5\|ηj\|<5 , is found to be σEW(ℓℓjj)=174±15(stat)±40(syst)\,fbσEW(ℓℓjj)=174±15(stat)±40(syst)\,fb , in agreement with the standard model prediction. The associated jet activity of the selected events is studied, in particular in a signal-enriched region of phase space, and the measurements are found to be in agreement with QCD predictions.
