Abstract: In this paper the Yennie-Frautschi-Suura approach is used to simulate realand virtual QED corrections in particle decays. It makes use of the universalstructure of soft photon corrections to resum the leading logarithmic QEDcorrections to all orders, and it allows a systematic correction of thisapproximate result to exact fixed order results from perturbation theory. Theapproach has been implemented as a Monte Carlo algorithm, which a posteriorimodifies decay matrix elements through the emission of varying numbers ofphotons. The corresponding computer code is incorporated into the SHERPA eventgenerator framework.
