Özet
This Letter reports measurements of differential cross sections for the production of two Z bosons in association with jets in proton-proton collisions at ?s = 8 and 13 TeV. The analysis is based on data samples collected at the LHC with the CMS detector, corresponding to integrated luminosities of 19.7 and 35.9 fb?1 at 8 and 13 TeV, respectively. The measurements are performed in the leptonic decay modes ZZ ? ` +` ?` 0+` 0?, where `, ` 0 = e, µ. The differential cross sections as a function of the jet multiplicity, the transverse momentum pT, and pseudorapidity of the pTleadin and subleading jets are presented. In addition, the differential cross sections as a function of variables sensitive to the vector boson scattering, such as the invariant mass of the two pT-leading jets and their pseudorapidity separation, are reported. The results are compared to theoretical predictions and found in good agreement within the theoretical and experimental uncertainties.
