Abstract

We discuss the significance of events containing rapidity-gaps in high-energy scattering processes, in particular in e+e- annihilation and/or W, Z decays. We compute explicitly the fraction of events containing rapidity-gaps in e+e- -->qqqq and e+e- -->qqgg processes at low jet-pair invariant mass limit. These events follow a distinctive sin2theta distribution in the jet-pair scattering angle. Similar processes are candidate backgrounds for important Higgs and W+W- scattering physics at the SSC and LHC.
