ResumoWe study the possibility to measure the anomalous couplings κ and λ in the WWγ three-boson vertex at HERA and LEP×LHC using the process ep→νγX. We discuss event distributions and their dependence on kinematical cuts in order to find observables with optimal sensitivity to the three-boson couplings. With an integrated luminosity of ∫ dt L=103 pb−1, HERA will be able to establish 2σ limits of κ = 1.0−1.7+1.9 and λ = 0−1.8+2.1. At LEP×LHC the corresponding limits are smaller and comparable to those from single W production in neutral current ep scattering.
