QCD Corrections to pp→ e⁻ν_e γ +jet — Francisco Campanario, •Christoph Englert, Michael Spannowsky, and Dieter Zeppenfeld — Institut für Theoretische Physik, Universität Karlsruhe

Searches for anomalous couplings at the LHC require a detailed knowledge of signal and background beyond leading-order analysis. Promising for anomalous WWγ couplings is the process pp→ Wγ, with a veto on hard additional jet activity. At present, however, this veto is based on the subtraction of a cross section at leading order QCD, with its concomitant scale uncertanties. We report on the calculation of the next-to-leading order QCD corrections to the process pp→ e⁻ν_e γ +jet, which represents the process vetoed for the WWγ coupling measurement.
