Abstract

The cross sections for the production of single W's and Z's via electroweak boson fusion are calculated for pp collisions at the Superconducting Super Collider (SSC). We present general event characteristics of the qq→qqW and qq→qqZ signals and the dominant backgrounds for leptonic decays of the W or Z. Special emphasis is given to the study of rapidity gap signatures, i.e., the existence of virtually hadron-free regions between the quark jets in the signal events. By measuring the rate at which rapidity gaps appear in W, Z production, the gap survival probability for electroweak signals can be determined. Thus, the feasibility of a rapidity gap trigger for the Higgs-boson search or for weak-boson scattering events can be verified directly at the SSC.
