Extended Electroweak Interactions and the Muon g μ − 2
We look at a number of simple, but representative, models of extended electroweak gauge structures, and present the general contributions to aμ 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 aμ and the Standard Model prediction if we require that the gauge fields explain the ...

متن کاملMuon ( g − 2 )
For a spin1 2 particle, ~ S = ~2~σ, and gs is called the Lande g-factor. From classical calculations that treat the charged particle as a rotating piece of current, gs = 1. Surprisingly, the Dirac equation in relativistic quantum mechanics predicts that gs = 2, a result which agreed with the crude experiments of the time. In the 1940’s, a new understanding of renormalization in the developing q...
متن کاملMuon g-2 and Implications for Supersymmetry
A brief review is given of the implications of the recent Brookhaven result on the muon anomaly ( aμ) for supersymmetry. We focus mainly on the implications of the recent results for the minimal supergravity unified model. We show that the observed difference implies the existence of sparticles most of which should become observable at the Large Hadron Collider. Further, as foreseen in works pr...
متن کاملLower Bound for Compactification Scale from Muon g − 2 in the Gauge-Higgs Unification
We discuss a muon anomalous magnetic moment in a five dimensional SU(3) gaugeHiggs unification compactified on M × S/Z2 space-time including Z2-odd bulk mass for a fermion. We calculate one-loop corrections to the anomalous magnetic moment of muon and find a lower bound for the compactification scale to be around 5 ∼ 6 TeV by comparing nonzero Kaluza-Klein mode contributions with the muon (g − ...
