Abstract
Lower bounds on the masses of neutral intermediate vector bosons within models augmenting known strong electromagnetic-weak interaction symmetries with an SU(2) symmetry unifying electron and muon or electron and mirror-electron families are derived from present constraints on rare processes. One such model, fully consistent with Glashow-Weinberg-Salam neutral current phenomenology, permits the occurrence of a neutral intermediate vector boson with a mass between 90 and 100 GeV accompanied by a lighter vectorlike partner whose mass is only minimally constrained by e +e −→μ +μ − asymmetry measurements. Alternatively, if the lighter neutral boson within the model has a mass of 89 GeV, then a heavier neutral intermediate vector boson may have a mass as low as 95 GeV, depending on the value for the gauge coupling of the “interfamilial” gauge symmetry.
