Weak gauge bosons above or straddling the standard-model masses in an SU(2) x U(1) x SU(2)' gauge model
We present a natural SU(2) x U(1) x SU(2)' gauge model with low-energy predictions identical to those of the standard model, but which allows all gauge-boson masses to be above or straddling their standard values. We discuss the Higgs structure and its relationship to the naturalness of the model. Current measurements of the e/sup +/e/sup -/..--> mu../sup +/..mu../sup -/ cross section set upper limits on the lightest W and Z masses of 89 and 116 GeV, respectively; from data on e/sup +/e/sup -/..-->..hadrons, the corresponding limits M/sub W//sub 1/<87 and M/sub Z//sub 1/<108 GeV are deduced. Some high-energy predictions for the model are explored. The model is extended to U(1) x SU(2)/sup N/ with all possible SU(2) x U(1) Higgs doublets and SU(2) x SU(2) Higgs quartets.
