The survival probability of large rapidity gaps in a three channel model

TL;DR

This paper calculates the energy-dependent survival probability of large rapidity gaps in high-energy collisions using a three channel model that accounts for various diffractive processes and elastic rescattering.

Contribution

It introduces a three channel model to compute the survival probability of large rapidity gaps, incorporating single and double diffractive production and elastic rescattering.

Findings

Survival probability decreases with increasing energy.

Weak energy dependence of the ratio (\sigma_{el}+\sigma_{SD})/\sigma_{tot}.

Results align with recent Tevatron data.

Abstract

The values and energy dependence for the survival probability $< \mid S\mid^2 >$ of large rapidity gaps (LRG) are calculated in a three channel model. This model includes single and double diffractive production, as well as elastic rescattering. It is shown that $< \mid S \mid^2 >$ decreases with increasing energy, in line with recent results for LRG dijet production at the Tevatron. This is in spite of the weak dependence on energy of the ratio $ (\sigma_{el}+ \sigma_{SD})/\sigma_{tot}$.
