Precise predictions for WH plus jet production at the LHC

We present precise predictions for the production of a Higgs boson in association with a hadronic jet and a W boson at hadron colliders. The behaviour of QCD corrections are studied for fiducial cross sections and distributions of the charged gauge boson and jet-related observables. The inclusive process (at least one resolved jet) and the exclusive process (exactly one resolved jet) are contrasted and discussed. The inclusion of QCD corrections up to O(alpha(3)(s)) leads to a clear stabilisation of the predictions and contributes substantially to a reduction of remaining theoretical uncertainties.

Automated summary

This study presents precise predictions for the production of a Higgs boson in association with a hadronic jet and a W boson at hadron colliders. The behavior of QCD corrections is investigated for fiducial cross sections and distributions of relevant observables. The inclusion of QCD corrections leads to a stabilization of the predictions and a reduction of theoretical uncertainties.
