Muon anomalous magnetic dipole moment in the minimal supersymmetric standard model

The muon anomalous magnetic dipole moment (MDM) is calculated in the framework of the minimal supersymmetric standard model (MSSM). In this paper, we discuss how the muon MDM depends on the parameters in the MSSM in detail. We show that the contribution of the superparticle loop becomes significant especially when tan beta is large. Numerically, it becomes of order 10(-8)-10(-9) in a wide parameter space, which is within the reach of the new Brookhaven E821 experiment.
