Multiple interactions and rapidity gap survival

TL;DR

This paper reviews calculations of the probability that large rapidity gaps in high-energy collider events remain intact despite secondary interactions and gluon radiation, which is crucial for understanding rare processes.

Contribution

It provides a comprehensive review of models estimating rapidity gap survival probabilities across various high-energy processes.

Findings

Survival probabilities vary significantly across different processes.

Soft interactions and gluon radiation reduce the likelihood of gap survival.

The review highlights the importance of these calculations for experimental observations.

Abstract

Observations of rare processes containing large rapidity gaps at high energy colliders may be exceptionally informative. However the cross sections of these events are small in comparison with that for the inclusive processes since there is a large probability that the gaps may be filled by secondary particles arising from additional soft interactions or from gluon radiation. Here we review the calculations of the probability that the gaps survive population by particles from these effects for a wide range of different processes.
