Theory of two Z bosons
The general theory of two-Z-boson electroweak models is developed, without using gauge theories. All low-energy neutral-current couplings are expressed in terms of the generalized Weinberg angle and other parameters. The sufficient condition for giving the same neutrino-induced neutral-current reactions as the Glashow-Weinberg-Salam (GWS) model does is obtained. The best place to see the deviation from the GWS model is the forward-backward asymmetry in e/sup +/e/sup -/..--> mu../sup +/..mu../sup -/. We find a model based on SU(2)/sub L/xU(1)/sub K/xU(1)/sub B/-L, which yields exactly the same predictions for charged-current reactions and neutrino-induced neutral-current reactions as the GWS model does and still gives the larger forward-backward asymmetry.
