Extended Electroweak Interactions and the Muon g-2

Abstract

We look at a number of simple, but representative, models of extended electroweak gauge structures, and present the general contributions to a_muon from the heavy Z' and W' electroweak gauge bosons. Of the models we have examined, none can explain the observed discrepancy between the current experimental value of a_muon and the Standard Model prediction if we require that the gauge fields explain the discrepancy by themselves. In the context of models with new matter fields as well as the additional gauge fields discussed here, however, the gauge field contributions to a_muon can be a substantial and important part of the discrepancy.
