Lepton flavor violation production of new particles from a topcolor scenario via e collision
Abstract:The topcolor scenario generally predicts the existence of the neutral top-pion 0t and the nonuniversal gauge boson Z', which have flavor changing couplings to ordinary fermions at tree-level. Taking into account the constraints of the lepton flavor violation (LFV) processes → e and → 3e on the relevant free parameters, we consider production of these new particles via the LFV processes e → 0t and e → Z' at the international linear e+e− collider (ILC) experiments. We find that the effective cross section for the LFV process e → 0t is smaller than 0.2fb. While, the effective cross section of the LFV process e → Z' can reach 12.2fb with reasonable values of the free parameters.
