Next-to-leading order QCD corrections toW+W+andW−W−production in association with two jets

We present a study of ${W}^{+}{W}^{+}jj$ and ${W}^{\ensuremath{-}}{W}^{\ensuremath{-}}jj$ production including leptonic decays in hadron-hadron collisions. The full electroweak and QCD induced contributions and their interferences are calculated at leading order. We find that, for inclusive cuts, the interference effects can be large if the jets are produced with large transverse momentum where, however, the production rate is suppressed. We also discuss the vector-boson-fusion cuts and show the validity of the vector-boson-fusion approximation. The next-to-leading order QCD corrections to the QCD-induced channels are also calculated. Compared to the previous calculation, we allow the inter…
