Real Time Radiative Corrections to Charged Particle Decay Laws

Abstract

The real time exponential decay laws for meta-stable charged particles are shown to require radiative corrections. The methods employed are well known to be valid for radiatively correcting Breit-Wigner line shapes. Radiative corrections contribute substantially to precision life time measurements of muons and pions when initially stopped in condensed matter.Comment: RevTeX File, 6 Pages, 5 Figure
