Prospects for Probing the Three Gauge-boson Couplings in W + Photon Production at the LHC

We assess the prospects for probing the WWgamma triple gauge-boson coupling directly by means of hadronic W+ photon production at the 14 TeV Large Hadron Collider (LHC) using the ATLAS detector. The expected confidence intervals for anomalous couplings are presented including the effects of higher order QCD corrections and the contributions from systematic effects. A strategy for reporting the anomalous couplings limits is introduced which removes the ambiguities of form factors, by reporting the limits as a function of a cutoff operating on the diboson system invariant mass. Techniques for measuring the energy dependence of anomalous couplings are demonstrated.
