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 particul arly relevant in the presence of light sleptons, charginos and neutral inos, especially in the large tan beta regime. For moderate or large v alues of tan beta, it is possible to rule out scenarios in which charg inos and sneutrinos are both light, but nevertheless escape detection at the LEP2 collider. Furthermore, models in which supersymmetry break ing is transferred to the observable sector through gauge interactions can be efficiently constrained by the (g - 2)(mu) measurement.
