Abstract

We analyze the production of a Higgs boson in association with a Z boson at hadron colliders in the Standard Model and some simple extensions. We show how multijet merging algorithms at leading and next-to-leading order for the loop-induced gluon fusion and the Drell-Yan-like quark-induced processes, respectively, improve the descriptions for various differential distributions, in particular those that involve the production of additional jets. The phenomenological studies focus on two relevant channels of Higgs boson decays, namely H→invisible and H→bb¯. We find sizable and phenomenologically relevant corrections to the transverse momentum and invariant mass distributions for the Higgs boson candidate. Thanks to the large destructive interference for the top Yukawa terms, this process is very sensitive to the magnitude and sign of a possible nonstandard top-Higgs coupling. We analyze the impact of this anomalous interaction on distributions and estimate constraints from LHC Run II.
