The best chance for detecting the Higgs boson at the LHC is through exclusive Higgs production in pp scattering, where the Higgs is produced in t-channel BFKL Pomeron exchange with no other production, creating large rapidity gaps between the Higgs and the emerging protons. The survival probability of the large rapidity gaps is derived by suppressing diagrams with additional parton showers, which give rise to additional inelastic scattering which fills up the large rapidity gaps. To accurately estimate the survival probability, one has to solve the long standing theoretical problem of summing over the complete set of Pomeron loop diagrams in QCD, in order to find the contribution of all hard re-scattering diagrams to the survival probability. The survival probability is crucial for LHC experiments aimed at detecting the Higgs signal, and the summation of loop diagrams in QCD is a big advance in high energy Physics both from an experimental and a theoretical point of view.
