The pion branching ratio, $R_{\pi} = \frac{\Gamma ( \pi^+ \to e^+ \nu_e + \pi^+ \to e^+ \nu_e \gamma)}{\Gamma (\pi^+ \to \mu^+ \nu_{\mu} + \pi^+ \to \mu^+ \nu_{\mu} \gamma)}$ , provides a sensitive test of lepton universality and constraints on many new physics scenarios. The theoretical uncertainty...
