） Abstract： We calculate the next-to-leading order(NLO) QCD corrections to the WH^0 production in association with a jet at hadron colliders
We study the impacts of the complete NLO QCD radiative corrections to the integrated cross sections, the scale dependence of the cross sections, and the differential cross sections ( dσ/dcos θ , dσ/dpT ) of the final W-, Higgs boson and jet
We find that the corrections significantly modify the physical observables, and reduce the scale uncertainty of the leading-order cross section
Our results show that by applying the inclusive scheme with p_{cut}^{T,j} = 20 GeV and taking m_H = 120 GeV , μ= μ_0 = 1/2 (mW + mH), the K-factor is 1
15 for the process ar{p}p o W^±H^0j + X at the Tevatron, while the K-factors for the processes pp o W^?H^0j+X and pp o W^+H^0j+X at the LHC are 1
12 and 1
08 respectively
We conclude that to understand the hadronic associated WH0 production, it is necessary to study the NLO QCD corrections to the WH^0j production process which is part of the inclusive WH^0 production
