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

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 $(\ddot{I}{ƒ}_{el}+\ddot{I}{ƒ}_{SD})/\ddot{I}{ƒ}_{tot}$.
