Multiple photon effects in fermion-(anti)fermion scattering at SSC   energies
  We use the theory of Yennie, Frautschi and Suura to realize, via Monte Carlo methods, the process $f\,\bbbarf\to f'\,\bbbarf'+n\gamma$ at SSC and LHC energies, where $f$ and $f'$ are quarks or leptons. QED infrared divergences are canceled to all orders in perturbation theory. The resulting Monte Carlo event generator, SSC-YFS2, is used to study the effects of initial-state photon radiation on these processes in the SSC environment. Sample Monte Carlo data are presented and discussed. We find that the respective multiple-photon effects must be taken into account in discussing precise predictions for SSC physics processes.
