Some Consequences of an SU(2) ⊗ U(1) Gauge Model

The experimental consequences of an SU(2) ⊗ U(1) model in which the intermediate-boson mass $m_W$ is bounded below by 13 GeV are discussed. For the special choice of $m_W=18\mathrm{}$ GeV neutral-current effects essentially disappear. The model includes a heavy neutral lepton of the muon type whose mass is bounded above and below by ∼ 1.2 GeV and 390 MeV, respectively. The model is thus relatively more accessible to experimental tests than other gauge models. Other aspects of the model are discussed.
