WH production at the LHC within SMEFT at next-to-next-to-leading order QCD

We study the impact of the pointlike qq'WH interactions originating from a subset of dimension-six operators of the Standard Model effective field theory (SMEFT) on the Higgs boson associated production pp -> W+H at the LHC. For consistency, we also take into account the corresponding qq'W vertices implied by these operators. We compute the next-to-next-to-leading order quantum chromodynamics (QCD) corrections to this process and compare these corrections in the Standard Model and SMEFT production mechanisms.
