Abstract

We present a next-to-leading order QCD calculation for e+ nu_e mu+ nu_mu jj and e- nubar_e mu- nubar_mu jj 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.
