One-loop QCD amplitudes for vector-boson-fusion Higgs-boson production to higher orders in $\epsilon$
We consider one-loop QCD corrections to Higgs-boson production via vector-boson fusion at hadron colliders. As an input for future exact NNLO computations, we derive the one-loop helicity amplitudes to higher orders in the dimensional regulator. We present a direct calculation of the amplitudes with spinor-helicity tec...
