Abstract: (Springer)
We present fully differential next-to-leading order results for Higgs production in association with a Z boson in gluon fusion. Our two-loop virtual contributions are evaluated numerically using sector decomposition, including full top-quark mass effects, and supplemented at high pT_{T} by an analytic high-energy expansion to order mZ4,mH4,mt32 {m}_Z^4,{m}_H^4,{m}_t^{32} . Using the expanded results we also present a study of the top-quark mass scheme uncertainty at large pT_{T}.
