CP-violating electric and weak dipole moments of theτlepton from threshold to 500 GeV

A number of $\mathrm{CP}$-odd momentum correlations are investigated for $\tau$ pair production in $e^{+}{e}^{-}$ collisions covering the energy range from threshold to 500 GeV. These correlations are in particular sensitive to the electric and weak dipole form factor of the $\tau$ lepton. Taking into account the main decay modes of the $\tau$, the correlations are calculated in terms of these form factors. Sensitivity estimates, which apply to present and future $e^{+}{e}^{-}$ facilities, are given.
