ZH production in gluon fusion at NLO in QCD

Abstract

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 by an analytic high-energy expansion to order m4Z,m4H,m32t. Using the expanded results we also present a study of the top-quark mass scheme uncertainty at large pT
