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

چکیده
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), γγ → τμ (or τe), ee → τμ, and eγ → eπ t → eτμ(e) via the flavor changing (FC) couplings π t lilj and discuss the possibility of searching for the LFV signals via these processes in future lepton colliders.

متن کاملThe neutral top-pion and the lepton flavor violating Z decays Z → lilj
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 s...

In the context of topcolor-assisted techicolor(TC2) models, we study the contributions of the neutral top-pion π t to the lepton flavor violating(LFV) processes li → ljγ and li → lj lkll. We find that the present experimental bound on μ → eγ gives severe constraints on the free parameters of TC2 models. Taking into account these constraints, we consider the processes li → lj lkll generated by t...

Many models, such as topcolor-assisted technicolor (TC2) models and flavoruniversal TC2 models, predict the existence of extra U(1) gauge bosons Z ′, which couple preferentially to the third generation. The lepton flavor violating (LFV) signals of these new particles at the future e+e− colliders (LCs) are discussed via calculating its contributions to the LFV process e+e− → μτ . We calculate th...
