Muon g-2 and precision electroweak physics in the MSSM
Gi-Chol Cho, Kaoru Hagiwara, Masashi Hayakawa
Abstract
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 (μ, M2)-plane that fit well to the electroweak data and give significant contribution to muon g-2.
