Pomeron loop summation in perturbative QCD and the survival probability

TL;DR

This paper calculates the survival probability of exclusive diffractive Higgs production in perturbative QCD by summing over Pomeron loops, revealing it decreases with energy and is very small at LHC energies.

Contribution

It introduces an iterative technique to sum over complex Pomeron loop diagrams in perturbative QCD for the first time.

Findings

Survival probability decreases with increasing energy.

At LHC energies, the probability is less than 1%.

The method accounts for short-distance interactions in the calculation.

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 %.
