  Vector-boson fusion and associated production at the LHC can provide key
information on the strength and structure of the Higgs couplings to the
Standard Model particles. Using an effective field theory approach, we study
the effects of next-to-leading order (NLO) QCD corrections matched to parton
shower on selected observables for various spin-0 hypotheses. We find that
inclusion of NLO corrections is needed to reduce the theoretical uncertainties
on total rates as well as to reliably predict the shapes of the distributions.
Our results are obtained in a fully automatic way via FeynRules and
MadGraph5_aMC@NLO.
