Constraints on supersymmetric models from the muon anomalous magnetic moment

We study the impact of present and future (g - 2)_#mu# measurements on supersymmetric models. The corrections to (g - 2)_#mu# become particularly relevant in the presence of light sleptons, charginos and neutralinos, especially in the large tan #beta# regime. For moderate or large values of tan #beta#, it is possible to rule out scenarios in which charginos and sneutrinos are both light, but nevertheless escape detection at the LEP2 collider. Furthermore, models in which supersymmetry breaking is transferred to the observable sector through gauge interactions can be efficiently constrained by the (g - 2)_#mu# measurement.
