Rapidity Gaps from Colour String Topologies

TL;DR

This paper discusses how soft colour exchange models explain rapidity gaps in diffractive scattering events by varying colour string topologies, providing a unified description of different final states in high-energy collisions.

Contribution

It introduces a unified model based on soft colour exchanges that accounts for rapidity gaps across various diffractive processes.

Findings

Soft colour exchange models successfully describe diffractive events.

Variation in colour string topologies explains gap formation.

Unified framework applies to multiple high-energy scattering processes.

Abstract

Diffractive deep inelastic scattering at HERA and diffractive W and jet production at the Tevatron are well described by soft colour exchange models. Their essence is the variation of colour string-field topologies giving both gap and no-gap events, with a smooth transition and thereby a unified description of all final states.
