Survival probability of large rapidity gaps in a three channel model

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