Measurement of triple gauge boson couplings a an e-gamma collider

Abstract

If no light Higgs boson exists, the interaction among the gauge bosons becomes strong at high energies (~1TeV). The effects of strong electroweak symmetry breaking (SEWSB) could manifest themselves indirectly as anomalous couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings is presented looking at the hadronic decay channel of the W boson at an e-gamma - collider. A sensitivity in the range of 10^{-3} to 10^{-4} can be reached depending on the coupling under consideration.
