Description
This talk is based on the main results of the published article JHEP 04 (2022) 152. Model independent bounds on new physics are obtained using semi-leptonic tau decays as observables. To do this, We determine the dependence of several inclusive and exclusive τ observables on the Wilson coefficients of the low-energy effective theory describing charged-current interactions between light quarks and leptons. These results are then combined with inputs from other low-energy precision observables. In particular, with nuclear beta, baryon, pion, and kaon decay data.
