Query: 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.
