Higgs-boson production through gluon fusion at NNLO QCD with parton showers

Abstract

We discuss how the ${\mathrm{UN}}^{2}\mathrm{LOPS}$ scheme for matching next-to-next-to-leading order (NNLO) calculations to parton showers can be applied to processes with large higher-order perturbative QCD corrections. We focus on Higgs-boson production through gluon fusion as an example. We also present an NNLO fixed-order event generator for this reaction.
