Description
In this talk I will present some recent developments in the calculation of the NLO QCD corrections for two gluon-initiated processes that are relevant for Higgs physics at the LHC, namely gg->ZH and gg->ZZ. The two-loop box diagrams with massive internal lines contributing to these amplitudes pose a technical challenge, and I will discuss their analytic calculation using a small-tansverse-momentum expansion, which also allows for a fast numerical evaluation of the QCD corrections.
