We describe a recent computation of next-to-leading order (NLO) QCD corrections to the gluonic production of two massive vector bosons, including both prompt gg → VV production and the Higgs-mediated production gg → H → VV, as well as their interference. Both massless and massive quark loops are considered, with the NLO corrections to the latter being treated in a large mass expansion. We present results in the sizable window between the Higgs and top production thresholds. The NLO corrections are large and similar in size for the signal, background, and interference processes. The NLO corrections are also roughly constant in the invariant mass of the diboson pair, except near the 2mV threshold, where the corrections to the interference change dramatically.
