摘要：

The minimal supersymmetric extension of standard model (MSSM) is examined by analyzing its quantum effects on the precision electroweak measurements and the muon g - 2. We examine carefully the effects of light charginos and neutralinos that are found to improve the fit to the electroweak data. We identify two distinct regions on the (mu, M-2)-plane that fit well to the electroweak data and give significant contribution to muon g - 2. (C) 2000 Elsevier Science B.V. All rights reserved.
