title: Dominant QCD backgrounds in Higgs boson analyses at the LHC: a study of pp --> tt + 2 jets at next-to-leading order.
abstract: We report the results of a next-to-leading order simulation of top quark pair production in association with two jets. With our inclusive cuts, we show that the corrections with respect to leading order are negative and small, reaching 11%. The error obtained by scale variation is of the same order. Additionally, we reproduce the result of a previous study of top quark pair production in association with a single jet.
