In this talk we study the sensitivity of exclusive hadronic tau decays to non-standard interactions using the low-energy limit of the Standard Model Effective Field Theory.
Employing Lattice input and dispersive form factors, along with experimental data, we analyze both one and two meson decays to set bounds on the new physics effective couplings.
Our results complement the traditional low-energy probes, such as nuclear $\beta$ or $K_{\ell3}$ decays, and can be improved with new data, e.g. from Belle-II.
