W+W−+ dijet to next-to-leading order in QCD

I present the calculation of the production of a W-boson pair in association with two jets at the Tevatron and LHC, performed to next-to-leading order in QCD. This is an important background in Higgs boson production, whether it occurs through gluon fusion or weak boson fusion. In this calculation, the W-bosons decay leptonically and all spin correlations are included. Although we find that the NLO QCD corrections modify the results for the default scale choice by only around 10-20%, we also see that they are responsible for a drastic decrease in the scale uncertainty associated with the results. For this reason, the NLO calculation allows for much greater accuracy in Higgs searches. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
