Measurement of the inclusive cross-section for the production of jets in association with a $Z$ boson in proton-proton collisions at 8 TeV using the ATLAS detector / ATLAS Collaboration
The inclusive cross-section for jet production in association with a $Z$ boson decaying into an electron-positron pair is measured as a function of the transverse momentum and the absolute rapidity of jets using 19.9 fb$^{-1}$ of $\sqrt{s} = 8$ TeV proton-proton collision data collected with the ATLAS detector at the Large Hadron Collider.
