Abstract
A very simple model based on γ-W 0 mixing (but not on spontaneously broken gauge symmetry) is shown to reproduce all the quantitative predictions of the standard (Weinberg-Salam) model as far as low-energy phenomenology is concerned. The model predicts intermediate-boson mass relations weaker than Weinberg's. Weinberg's mass formulae, however, can be accommodated in our model provided the γ-W 0 mixing parameter and the coupling constants ( e and g) satisfy a special relation. This relation also guarantees asymptotic SU(2) × U(1), decent high-energy behavior in processes like v + v → W + + W − and the SU(2) × U(1) value for the W ± boson gyromagnetic ratio. Speculative attempts are made to understand the sign and magnitude of “sin 2 θ W”.
