The Tau leptons, because of their large mass and relatively long life-time offer unique opportunities for precision tests of Standard Model and its extensions both in the investigation of their decays (where properties of the strong interactions at intermediate energies can be studied) and in their production. To perform such tasks the preparation of new theoretical and in particular Monte Carlo tools are needed.
In the following I will address the points necessary for the evaluation of low energy hadronic interactions in the dynamic of tau decaysand for the measurements of anomalous magnetic and electric dipole moments of taus.
