ZH production in gluon fusion at NLO in QCD.

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 p_T by an analytic high-energy expansion to order 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 p_T. [ABSTRACT FROM AUTHOR]
