Measurement of electroweak production of two jets in association with a Z boson in proton–proton collisions at √s = 8 TeV
The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton–proton collisions at √s = 8 TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 fb[superscript -1]. The electrow...

description | The purely electroweak (EW) cross section for the production of two jets in association with a Z boson, in proton–proton collisions at √s = 8 TeV, is measured using data recorded by the CMS experiment at the CERN LHC, corresponding to an integrated luminosity of 19.7 fb[superscript -1]. The electroweak cross section for the ℓℓ[subscript jj] final state (with ℓ = e or μ and j representing the quarks produced in the hard interaction) in the kinematic region defined by M[subscript ℓℓ] > 50 GeV, M[subscript jj] > 120 GeV, transverse momentum p[subscript Tj] > 25 GeV, and pseudorapidity |η[subscript j]|<5, is found to be σ[subscript EW](ℓℓ[subscript jj]) = 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. |
