Abstract

We show that weak-interaction gauge-theory renormalization corrections are negligible, and that explicit model dependences are small for the ratio

\frac{Γ (π \to e ν or e ν γ)}{Γ (π \to μ ν or μ ν γ)}

. We use the postulate that this continues to hold for other pseudoscalar mesons to justify examining these radiative corrections for

π

,

K

, and

D

in a phenomenological fashion.
