${{\mathit \tau}}$ WEAK ANOMALOUS MAGNETIC DIPOLE MOMENT ($\alpha {}^{\mathit w}_{{{\mathit \tau}}}$)

Electroweak radiative corrections are expected to contribute at the $10^{-6}$ level. See BERNABEU 1995.
The $\mathit q{}^{2}$ dependence is expected to be small providing no thresholds are nearby.
