WEAK DIPOLE MOMENTS AT ${\mathbf{e}}^{+}{\mathbf{e}}^{-}$ COLLIDERS

The weak dipole moments of leptons and quarks, \ie those related to their $Z$–coupling, are reviewed. Standard Model predictions and experimental results may result in a stringent test for both their pointlike structure and also for the Standard Model. Special attention is devoted to the anomalous weak–magnetic dipole moment and to the $CP$–violating weak–electric dipole moment.
