Abstract

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 tanβ is large. Numerically, it becomes of order 108-109 in a wide parameter space, which is within the reach of the new Brookhaven E821 experiment.
