چکیده
We show that in supersymmetric models with explicit flavor lepton number violation due to soft supersymmetry breaking mass terms there must be flavor lepton number violation in slepton decays. We propose to look for flavor lepton number violation in righthanded selectron and smuon decays. For selectron and smuon lighter than 80 Gev flavor lepton number violation in slepton decays could be discovered at LEP2 provided the mixing between selectron and smuon is not small. We also estimate NLC discovery potential of the lepton flavor number violation in slepton decays.

Neutrino oscillations give clear evidence for non-vanishing neutrino masses and lepton-flavor violation (LFV) in the neutrino sector. This provides strong motivation to search for signals of LFV also in the charged lepton sector, and to probe the SUSY seesaw mechanism. We compare the sensitivity of rare radiative decays on the right-handed Majorana mass scale MR with the reach in slepton-pair p...

Lepton flavor violation can be induced in supersymmetry by the mixing of two or more of the leptonic scalar partners, l̃ → l̃, where l̃, l̃ = ẽ, μ̃, τ̃ . Krashnikov and ArkaniHamed et al. pointed out that this effect may be observable at the Next Linear Collider, through slepton pair production with subsequent lepton flavor violating decays. If the slepton mixing involves all three generations, CP vi...

We study lepton-flavor violating slepton production and decay at a future e+e− linear collider in context with the seesaw mechanism in mSUGRA post-LEP benchmark scenarios. The present knowledge in the neutrino sector as well as improved future measurements are taken into account. We calculate the signal cross-sections σ(e±e− → l β l− α χ̃b χ̃a); lδ = e, μ, τ ; α 6= β and estimate the main backgro...
