  We study the impact of dimension-six operators of the standard model
effective field theory relevant for vector-boson fusion and associated Higgs
boson production at the LHC. We present predictions at the next-to-leading
order accuracy in QCD that include matching to parton showers and that rely on
fully automated simulations. We show the importance of the subsequent reduction
of the theoretical uncertainties in improving the possible discrimination
between effective field theory and standard model results, and we demonstrate
that the range of the Wilson coefficient values allowed by a global fit to LEP
and LHC Run~I data can be further constrained by LHC Run~II future results.
