Probing New Gauge Boson Couplings via Three-Body Decays

الأصل · EN

We examine the possibility of using rare, 3-body decays of a new neutral gauge boson,, to probe its gauge couplings at hadron colliders. Specifically, we study the decays → Wℓν and → Zνν and find that much knowledge of the properties can be obtained from these processes. In particular, these decay modes can yield valuable information on the amount of Z₁-Z₂ mixing, on the generation dependence of the couplings, on the properties of the new generator associated with the, as well as being used to distinguish between possible extended models. The analogous 3-body decays into a new, heavy charged gauge boson, → W₂±ℓ∓ν, are also investigated in models where this can occur.
