Description
Pair production of Z bosons is an essential process at the LHC. It is a significant background to Higgs production, and subsequent decay through the four lepton channel, as well as an important signal process for new physics searches. In this talk, we present our calculation of the next-to-leading order QCD corrections to Z-pair production through gluon fusion with full top quark mass dependence. We discuss the details of the calculation of the challenging two-loop virtual amplitudes. We then present phenomenological results for this process.
