Production of three vector bosons in e+ e- annihilation as a test of W+/-, Z, γ self-interactions
We study the vector-boson production processes e+e--->W+W-Z and e+e--->W+W-γ which are directly affected by the trilinear and quadrilinear self-couplings of the W+/-, Z and γ. Our analysis is based upon a single-parameter effective lagrangian model for these self-interactions which contains the standard model as a special case. Consequences for the phenomenology at an e+e- collider of 500 GeV (NLC) are discussed, and fits of the free parameter around its standard model value are carried out.
