Query: Lepton flavor violating signals of gauge bosons $Z^{\prime}$ at future
  $e^{+}e^{-}$ colliders   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 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 $e^{+}e^{-}\to\mu\tau$. We calculate the cross section of this
process and discuss its dependence on the beam polarization. The ratio of
signal over square root of the background $(S/\sqrt{B})$ is also calculated.
The results show that the LFV signals of the gauge bosons $Z^{\prime}$ may be
detected at the future LC experiments.
