Electroweak corrections to W+W-Z and ZZZ production at the linear collider†

We calculate the electroweak corrections to the production of W+W-Z and ZZZ at the linear collider in the Standard Model. These processes are important for the extraction of the quartic couplings of the massive gauge bosons which can be a window on the mechanism of spontaneous symmetry breaking. We find that the weak corrections to some kinematic distributions show new features and hence cannot be explained by an overall scale factor.
