Recent results and the current situation on the search for lepton-flavor-violating τ decays are presented. Bfactories have successfully accumulated data samples of > 10 9 τ pairs, and recently performed searches for τ → 3 , V 0 and f0(980). The upper limit of the branching ratio was obtained to be ∼

✦ Synopsis
Lepton flavor violation (LFV) in the charged sector has been gaining great interests these days. Experimental researches looking for muon LFV such as MEG and MECO are in preparation, and aiming to discover the muon LFV signal within this decade. There is also another activity called PRISM/PRIME project underway, which aims to expand muon LFV research furthermore. The status of those experimental studies will be described. The idea of building Muon Factory and its relevance to the future of neutrino physics is also commented upon.

In light of the discovery of neutrino oscillations, charged-lepton flavor violating (CLFV) processes (like μ → eγ and μ → e-conversion in nuclei) are guaranteed to occur. The rates for such processes, however, depend dramatically on the mechanism behind neutrino masses and on whether there are new d
MEG will test Lepton Flavor Violation in the μ → e + γ down to an unprecedendet sensitivity. After an introduction to various scenarios of physics beyond the Standard Model suggesting the possibility of LFV processes at a measurable level, the possibility of future experiments more sensitive to new
The current status of the experimental search for lepton flavor violation in rare muon decays is reviewed. The possible benefits of increasing the muon source intensity is examined for the different experimental situations.
The ratio R K = Γ(K ± → e ± ν)/Γ(K ± → μ ± ν) between the two leptonic decay rates of charged kaons is precisely predicted within the Standard Model (SM). A recent theoretical work noticed that SUSY extensions of the SM can induce mu-electron universality violation in such a way to introduce a shift
