Trilinear Gauge Couplings from gamma/gamma to WW
Abstract
If there is no the Standard Model Higgs boson, the interaction among the gauge bosons becomes strong at high energies (~ 1TeV). The effects of strong electroweak symmetry breaking could manifest themselves indirectly through the vertices as anomalous gauge boson couplings before they give rise to new physical states like resonances. Here a study of the measurement of trilinear gauge couplings kappagamma and lambdagamma is presented looking at the hadronic decay channel of the WW boson pair at an gamma/gamma-collider. A sensitivity of order of 0.001-0.0001 can be reached depending on the coupling under consideration and on the initial polarisation state.
