摘要: The process [ital pp][sup ([minus])][r arrow][ital W][sup [plus minus]][gamma]+[ital X][r l][sup minus]][nu][gamma]+[ital X] is calculated to O]([alpha][sub s]]) for general CP]-conserving WW][gamma] couplings. At the Fermilab Tevatron center-of-mass energy, QCD corrections W][sub [gamma]] production are modest, and Born inclusive cross sections have similar sensitivities effects of anomalous supercollider energies, large at high photon transverse momenta, reducing sensitivity nonstandard couplings by up a factor 2. size can be reduced significantly, fraction lost regained, if jet veto imposed.
