Abstract: (APS)
Using the current value for the pion lifetime, we have recomputed the branching ratio for π→eν decay obtained from the 1963 experiment of Di Capua et al. and find Γ(π→eν+π→eνγ)Γ(π→μν)=(1.274±0.024)×10−4, a change of 2%. The theoretically predicted value lies within two standard deviations, compared to the ½ standard deviation reported previously.References(5)
