Lepton flavor violating signals of gauge bosons $Z^{\prime }$ at future $e^{+}{e}^{-}$ colliders

Chongxing Yue, Yanming Zhang, Hong Li

Many models, such as topcolor-assisted technicolor (TC2) models and flavor-universal TC2 models, predict the existence of extra U(1) gauge bosons $Z^{\prime }$, which couple prefere…
