Testing anomalous WW{gamma} couplings in radiative charged current ep scattering

Technical Report:

Abstract

We study the possibility to measure the anamalous couplings {kappa} and {lambda} in the WW{Upsilon} three-boson vertex at HERA and LEP x LHC using the process ep {yields} v{Upsilon}X. 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 {Psi} dt L = 10{sup 3}pb{sup -1}, HERA will be able to establish 2{sigma} limits of {kappa} = 1.0{sup +1,9}{sub -1,7} and {lambda} = 0{sup +2,1}{sub -1,8}. At LEP x LHC the corresponding limits are smaller and comparable to those from single W production in neutral current ep scattering. (orig.).
