The capability of current and future measurements at low and high energy ${e}^{+}{e}^{\ensuremath{-}}$ colliders to probe for the existence of anomalous, $\mathrm{CP}$-conserving, $\ensuremath{\tau}\ensuremath{\nu}W$ dipole moment-type couplings is examined. At present, constraints on the universality of the $\ensuremath{\tau}$ charged and neutral current interactions as well as the shape of the $\ensuremath{\tau}\ensuremath{\rightarrow}\mathcal{l}$ …
