Contribution

It provides a comprehensive review of radiative corrections in tau meson decays and discusses their impact on fundamental SM tests and potential new physics signals.

Findings

Radiative corrections significantly affect tau decay measurements.

Implications for testing lepton universality and CKM unitarity.

Potential to identify non-standard interactions.

Abstract

We review the radiative corrections to the $\tau \to P (P) \nu_\tau [\gamma]$ decays and their implications for several SM tests: lepton universality, CKM unitarity and non-standard interactions.
