Next-to-leading order QCD corrections to W+ W+ jj and W- W- jj production via weak-boson fusion

We present a next-to-leading order QCD calculation for e+νeμ+νμ jj and e-ν̄eμ-ν̄μjj production via weak-boson fusion at a hadron collider in the form of a fully flexible parton-level Monte Carlo program, which allows for the calculation of experimentally accessible observables within realistic selection cuts. The QCD corrections to the integrated cross sections are found to be modest, while the shapes of some kinematical distributions change appreciably compared to leading order. The residual scale uncertainties of the next-to-leading order results are at the few-percent level. © 2009 The American Physical Society.
