Description
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 GAMMA (π → eν + π → eνγ) / GAMMA (π → μν) = (1.274 plus-or-minus 0.024) times 10-4, a change of 2%. The theoretically predicted value lies within two standard deviations, compared to the 1/2 standard deviation reported previously
