Abstract

Because the LHC is a proton-proton collider, sizable production of two positively charged W-bosons in association with two jets is possible. This process leads to a distinct signature of same sign high-p(perpendicular to) leptons, missing energy and jets. We compute the NLO QCD corrections to the QCD-mediated part of pp -> W(+)W(+)jj. These corrections reduce the dependence of the production cross-section on the renormalization and factorization scale to about +/- 10 percent. We find that a large number of W(+)W(+)jj events contain a relatively hard third jet. The presence of this jet should help to either pick up the W(+)W(+)jj signal or to reject it as an unwanted background.
