Pomeron loop summation in perturbative QCD and the survival probability

Abstract

The survival probability for exclusive diffractive Higgs production is calculated. The contribution of short distance interactions are taken into account, by summing over Pomeron loops in perturbative QCD. The summation is performed by developing an iterative technique to sum over loop diagrams with higher and higher generations of loops. The results show that the survival probability depends inversely on energy and is small for the LHC range of energies, and could be even less than 1 %.
