We studied lepton flavor violation in physics beyond the standard model. Especially in the Randall-Sundrum type extra-dimension scenario, we showed that the μ→ eγ decay branching ratio becomes large. The loop diagrams mediated by Kaluza-Klein modes of the bulk neutrinos, which are introduced so as to generate tiny neutrino masses, are large and we obtained a severe constraint on the mass of the lowest Kaluza-Klein mode i.e. mKK〓25TeV. For the τ lepton physics, we analyzed P and CP violation of τ decays in model independent way. We calculated the differential cross sections of the processes in which one of the pair created τ particles at an e+e- collider decays into lepton flavor violating final states e.g. τ → μγ, τ → 3μ, τ → μee. Using the correlations between angular distributions of both sides of τ decays, we can obtain information on parity and CP violations of lepton flavor non-conserving interactions. We also studied the muon-electron conversion process in nuclei. With values in this thesis, we can calculate the μ-e conversion rate in any models for each nucleus. We find that the conversion branching ratio has a tendency that it is larger in the nuclei with moderate atomic number than that in light or heavy nuclei. |
