Abstract

A simple spontaneously broken gauge model of electromagnetic and weak interactions without neutral currents has recently been constructed by Georgi and Glashow. Models of this sort characteristically contain a variety of hypothetical particles: intermediate vector bosons, one or more massive scalars, heavy leptons, charmed hadrons. In this paper we show that the agreement between the conventional calculation of muon $g\ensuremath{-}2$ and experimental data imposes relations among the masses of the intermediate vector meson, the heavy leptons associated with the muon, and the Higgs scalar meson, in the Georgi-Glashow model. We also deduce additional constraints on models of this sort from muonic atom data, and we briefly discuss scattering phenomena involving the presently unobserved particles of the Georgi-Glashow model.
