Abstract
Measurements of the production cross section of a $$Z$$ Z boson in association with jets in proton–proton collisions at $$\sqrt{s} = 13$$ s = 13 TeV are presented, using data corresponding to an integrated luminosity of 3.16 fb $$^{-1}$$ - 1 collected by the ATLAS experiment at the CERN Large Hadron Collider in 2015. Inclusive and differential cross sections are measured for events containing a $$Z$$ Z boson decaying to electrons or muons and produced in association with up to seven jets with $$p_{\text {T}} > 30$$ p T > 30 GeV and $$|y| <2.5$$ | y | < 2.5 . Predictions from different Monte Carlo generators based on leading-order and next-to-leading-order matrix elements for up to two additional partons interfaced with parton shower and fixed-order predictions at next-to-leading order and next-to-next-to-leading order are compared with the measured cross sections. Good agreement within the uncertainties is observed for most of the modelled quantities, in particular with the generators which use next-to-leading-order matrix elements and the more recent next-to-next-to-leading-order fixed-order predictions.
