Lepton number violation in tau lepton decays

.Lepton Flavor Violation and Rare Tau Decays*

We point out that the good statistics promised by the proposed Tau-Charm Factory for tau lepton pair prduction close to threshold, in combination with the high purity of the tagged sample, opens a window onto new physics phenomena: lepton flavor violation involving the third family of basic fermions may have uniquely interesting implications not accessible in interactions under scrutiny elsewhere.

Lepton Flavor Violating Decays – Review & Outlook 1. Why Lepton Flavor Violation? 2. Lfv Tau Decays

Here I review the status and prospects of experimental investigations into lepton flavor violation (LFV) in charged leptons. Rare LFV processes are naturally expected to occur through loops of TeV scale particles predicted by supersymmetric theories or other models beyond the Standard Model. In contrast to physics of quark flavors that is dominated by the Cabibbo-Kobayashi-Maskawa matrix, LFV i...

Lepton Number Violation in Decays of Supersymmetric Particles

We discuss lepton flavour violating signals at the LHC in the framework of supersymmetric theories. We consider R-parity conserving as well as R-parity violating scenarios. In the case of R-parity conservation we show that in decays of supersymmetric particles large regions in parameter exist where lepton flavour violating decay modes have large branching ratios despite the stringent constraint...
