چکیده
We consider the lepton-flavor violating(LFV) processes li → ljγ in the framework of topcolor assisted technicolor(TC2) models. We find that the new gauge boson Z ′ predicted by TC2 models can give significantly contributions to these processes via the flavor changing couplings. The present experimental bound on the LFV process μ → eγ gives severe constraints on the lepton mixing factors Kτe and Kτμ. The constraints from μ → eγ on TC2 models are stronger than those from μ → 3e. The future LFV experiments will be probes of TC2 models.

In the coming years, experiments underway will increase the sensitivity to charged lepton flavor violation by four orders of magnitude. These experiments will stringently probe weak scale physics. I review the status of global symmetries in the standard model and present several well-motivated models that predict observable lepton flavor violation. Finally, I describe what we might learn from f...

We consider the flavor changing neutral current(FCNC) process e+e− → t̄c(or tc̄) in the context of topcolor-assisted technicolor(TC2) models. We find that the contributions of charged scalars (technipions and top-pions) and topcolor gauge bosons are negligibly small. The neutral scalars (top-pion π0 t and top-Higgs h 0 t ) can give significant contributions to this process. With reasonable values...

We review the status of hard interactions, in particular of jet and heavy flavor production , at HERA and LEP. Emphasis is given to recent theoretical developments. Instantons, event shapes, and prompt photons are also briefly discussed.

Lepton flavor violating decays Z → µτ and J/Ψ, Υ → µτ are considered. It is shown that these decays can reach sizeable magnitudes if some specific lepton-flavor violating 4-fermion operators are generated by low scale quantum gravity effects, or by some other new physics at a TeV scale.
