Cross section for the production of Z pairs at hadron colliders as a function of the collider operating energy. The predictions of MCFM are compared with Tevatron data taken in proton-antiproton collisions at 1.96 TeV and with proton-proton LHC data at 7 and 8 TeV. Image courtesy of ATLAS At the LHC, a single collision between beams of protons produces an event containing a spray of particles that can be detected by the experiments. Each event may contain any of…
