Description
Several experimental collaborations have recently invested considerable effort in precision studies of hadronic tau decays.
With further improvements expected at Belle-II, it is important to discuss the theoretical implications of these experimental advances. In this talk, I will review several such implications. First, we will show that hadronic tau decays represent a clean laboratory
for the precise study of Quantum Chromodynamics (QCD) in its non perturbative regime.
Second, these decays can be used as a probe of the electroweak interaction. In this respect, we will discuss how tau decays and in particular $\tau \to \ell \pi \pi$ decays can be an interesting probe for lepton flavour violation allowing to unveil new phenomena.
