Measurement of differential cross sections for Z boson pair production in association with jets at and 13 TeV
Here, this Letter reports measurements of differential cross sections for the production of two Z bosons in association with jets in proton-proton collisions at $$\sqrt{s} =$$ 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 $$\to\ell^+ \ell^- \ell'^+ \ell'^-$$, where $$\ell,\ell' =$$ e, $$\mu$$. The differential cross sections as a function of the jet multiplicity, the transverse momentum $$p_\mathrm{T}$$, and pseudorapidity of the $$p_\mathrm{T}$$-leading 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 $$p_\mathrm{T}$$-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.
