Abstract
An exclusive event generator is designed for e + e − scan experiments, including initial state radiation effects up to the second order correction. The generator is coded within the framework of BesEvtGen. There are seventy hadronic decay modes available, with effective center-of-mass energy coverage from the two pion mass threshold up to about 6 GeV. The accuracy achieved for the initial state radiation correction reaches the level achieved by the KKMC generator. The uncertainty associated with the calculation of the correction factor to the initial state radiation is dominated by the measurements of the energy-dependent Born cross section.

The infrared divergence phenomena and high-energy processes

TL;DR: In this article, a general treatment of the infrared divergence problem in quantum electrodynamics is given, where the main feature of this treatment is the separation of infrared divergences as multiplicative factors, which are treated to all order of perturbation theory, and the conversion of the residual perturbations expansion into one which has no infrared divergence, and hence no need for an infrared cutoff.
