QCD corrections to hadronic Wγ production with nonstandard WWγ couplings

The process pp(¯)→W^±γ+X→ℓ^±νγ+X is calculated to O(α_s) for general CP-conserving WWγ couplings. At the Fermilab Tevatron center-of-mass energy, the QCD corrections to Wγ production are modest, and the Born and inclusive O(α_s) cross sections have similar sensitivities to the effects of anomalous couplings. At supercollider energies, the inclusive QCD corrections are large at high photon transverse momenta, reducing the sensitivity to nonstandard WWγ couplings by up to a factor 2. The size of the QCD corrections can be reduced significantly, and a large fraction of the sensitivity lost can be regained, if a jet veto is imposed.
