Abstract
We use the theory of Yennie, Frautschi, and Suura to realize, via Monte Carlo methods, the process ff(¯)→f′f(¯)′+nγ at energies reached at the Superconducting Super Collider (SSC) and the CERN Large Hadron Collider, 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.
