| dc.description | The supersymmetric contribution to the muon g-2 is studied in light of the finalization of the LEP electroweak precision data. The recent precise measurement of the muon g-2 of E821 experiment is explained well by the relatively light chargino and sleptons. We find that such the MSSM parameter space is also favored from the electroweak precision data, in which the fit to the data is better than that of the SM (Δχ^2_{min} \sim -2), if the lighter chargino has a mixed higgsino-wino character (μ/M_2 \sim 1). The models with light gauginos (μ/M_2 > 10) or light higgsinos (μ/M_2 < 0.1) also show the better fit over the SM, but the improvement is marginal as compared to the case of the mixed higgsino-wino case (μ/M_2 \sim 1). | |
