| Abstract: | We examine a class of gauge theories based on U(1)×SU(2)×G allowing for an arbitrary number of gauge bosons, while retaining the lowq 2 four fermion interaction of the standard model. Measurable consequences fore + e ?→μ + μ ? ande + e ?→e + e ? at presently available as well as LEP energies are presented. Implications of the recently determined QED cut-offΛ ? ? 100 GeV on gauge boson properties and the anomalous magnetic moment of the muon are pointed out. |
