چکیده

Taking into account the constraints of the present experimental limit of the process μ → eγ on the free parameters of topcolor-assisted technicolor(TC2) models, we calculate the contributions of the neutral top-pion to the lepton flavor violating(LFV) Z decays Z → lilj. Our results show that the value of the branching ratio Br(Z → τ l) is larger than that of Br(Z → μe) in all of the parameter space and there is Br(Z → τμ) ≈ Br(Z → τe) ≃ 2 × 10, which is far from the reach of present or future experiments.

Lepton flavor violating signals of the neutral top-pion in future lepton colliders

The presence of the top-pions π t in the low-energy spectrum is an inevitable feature of the topcolor scenario. Taking into account the constraints of the present experimental limit of the lepton flavor violating(LFV ) process μ → eγ on the free parameters of topcolor-assisted techicolor(TC2) models, we study the contributions of the neutral top-pion π t to the LFV processes μ μ → τμ ( or τe), ...

The contributions of the neutral top-pion π t and the non-universal gauge boson Z ′ predicted by topcolor scenario to the lepton flavor violating (LFV ) semileptonic τ decays τ → lP (V ) (P = π, η, η′ and V = ρ, φ) are discussed. We find that the contributions of Z ′ to these decay processes are generally larger than those from π t . π 0 t can only make the value of the branching ratio Br(τ → l...

New bounds on trilinear R-parity violation from lepton flavor violating observables

Many extensions of the leptonic sector of the Minimal Supersymmetric Standard Model (MSSM) are known, most of them leading to observable flavor violating effects. It has been recently shown that the 1-loop contributions to lepton flavor violating three-body decays li → 3lj involving the Z 0 boson may be dominant, that is, much more important than the usual photonic penguins. Other processes lik...
