Abstract

Simple dynamics, few available decay channels, and highly controlled radiative and loop corrections, make pion and muon decays a sensitive means of exploring details of the underlying symmetries. We review the current status of the rare decays: π+ → e+ν (πe2), π+ → e+νγ (πe2γ), π+ → π0e+ν (πe3), and [Formula: see text]. For the latter we report new preliminary values for the branching ratio B(Eγ > 10 MeV , θeγ > 30°) = 4.365 (9) stat (42) syst × 10-3, and the decay parameter [Formula: see text], both in excellent agreement with standard model predictions. We review recent measurements, particularly by the PIBETA and PEN experiments, and near-term prospects for improvement. These and other similar precise low energy studies complement modern collider results materially.
