Indirect Search for Supersymmetry

Effects of supersymmetric particles may appear in various low energy experiments through loop diagrams. We discuss various flavor changing neutral current processes, the muon anomalous magnetic moment and lepton flavor violation in the context of the supergravity model. In particular the $B^0$-$\ol{B}^0$ mixing and the muon anomalous magnetic moment are revisited taking into account the recent Higgs boson search result. We also consider $\mu^+ \to e^+ \gamma$ and $\mu^+ \to e^+ e^+ e^-$ processes with polarized muons. We calculate the P-odd and T-odd asymmetries in these processes for SU(5) and SO(10) supersymmetric grand unified theories and show that these asymmetries are useful to distinguish different models.
