Muon g-2 and implications for supersymmetry

Abstract

A brief review is given of the implications of the recent Brookhaven result on the muon anomaly (a μ) 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 prior to the Brookhaven experiment, the sign of the difference between experimental prediction of a μ and its Standard Model value determines the sign of the Higgs mixing parameter μ. The μ sign has important implications for the direct detection of dark matter. Implications of the Brookhaven result for other low-energy phenomena are also discussed.
