The recent results from Belle of the τ − → ντπ −e +e − analysis have incentivated us to make a reanalysis of a former work where the Structure Dependent parts are obtained using Resonance Chiral Theory. Here we rely on the same theory accounting for effects that explicitly break such symmetry. A motivation is the involved W πγ? vertex, utterly relevant in computing τ − → ντπ − radiative corrections.
