Contribution

It provides a comprehensive review of high-t diffraction processes, highlighting their significance in understanding gap production mechanisms in QCD.

Findings

Summarizes the status of theoretical models of high-t diffraction.

Reviews experimental results related to high-t diffraction.

Discusses the applicability of QCD perturbation theory to these processes.

Abstract

The study of those rapidity gap processes where a large momentum is transferred across the rapidity gap provides an ideal opportunity to understand the gap producing mechanism wholly within the framework of QCD perturbation theory. The current theoretical and experimental status of this `high-t diffraction' is reviewed.
