Lepton flavor violation production of new particles from a topcolor scenario via eγ collision
Chong-Xing Yue, Hui-Di Yang and Hao-Lin Feng
Show affiliationsThe topcolor scenario generally predicts the existence of the neutral top-pion π0t 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 μ → eγ and μ → 3e on the relevant free parameters, we consider production of these new particles via the LFV processes eγ → τπ0t and eγ → τZ' at the international linear e+e− collider (ILC) experiments. We find that the effective cross section for the LFV process eγ → τπ0t is smaller than 0.2fb. While, the effective cross section of the LFV process eγ → τZ' can reach 12.2fb with reasonable values of the free parameters.
