摘要：With the help of a physically motivated ansatz, which is fitted to the data, we estimate the size of
possible duality violations in hadronic tau decay. The result is that the uncertainty associated with
these violations could impact the as determination from the total decay width at a level which we
estimate to be das(mt ) ∼ 0.003−0.010. Consequently, it cannot be neglected.
