Testing The WWγ Coupling at Future Multi-TeV pp-Colliders

Part of the Ettore Majorana International Science Series book series (EMISS, volume 44)


The structure of the WW γ vertex can be measured in W± γ production at future multi-TeV pp-colliders. Deviations from the gauge theory structure can be parametrized in terms of 4 form factors whose high-energy behavior is severly limited by unitarity. Signatures of these anomalous couplings are described and it is found that multi-TeV hadron colliders can improve the measurement of the WW γ vertex by up to two orders of magnitude beyond what is expected from e + e - →W + W - at LEP200.
