The $e^{-} e^{-}$ mode of LC: opportunities to discover loop-level lepton flavor (number) violation

M. Cannoni, O. Panella, St. Kolb

The $e^{-} e^{-}$ mode with lepton number $L = + 2$ of the initial state is particularly suitable for studying lepton and flavor number violating reactions (LFV). In this brief report we…

Charge asymmetry in $γγ \to μ^{+} μ^{-} + neutrinos$ with polarized photons

D. A. Anipko, M. Cannoni, I. F. Ginzburg +2

The difference in distributions of $μ^{+}$ and $μ^{-}$ in reactions $γ γ \to μ^{+} μ^{-} + ν ν ˉ$ and $γ γ \to W^{\pm} μ^{\mp} + ν (ν ˉ)$ with polarized photons at $s > 200$ GeV is a large obser…

Loop level lepton flavor violation at linear colliders

Mirco Cannoni, Orlando Panella, Stephan Kolb

We present a study of loop-level lepton flavor vioalting signals in models with heavy Majorana neutrinos and in the supersymmetric extension of the standard model. The attention is…

Constraints on Composite-Models Effective Lagrangians from Neutrinoless Double Beta Decay

Orlando Panella

We give a brief review of the existing bounds on effective couplings for excited states ( $e^{*}, ν^{*}, u^{*}, d^{*}$ ) of the ordinary quarks and leptons arising from a composite model sc…
