Precise predictions for WH+jet production at the LHC

Abstract 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 ( α s 3 ) leads to a clear stabilisation of the predictions and contributes substantially to a reduction of remaining theoretical uncertainties.
