Double diffraction production for dipole-dipole scattering at high energies
Abstract
This paper is a first attempt to describe double diffractive production in dipole-dipole scattering within high energy QCD. Our approach is based on summing large BFKL Pomeron loops, which generate two clusters of hadrons separated by a rapidity gap. Unlike in the BK framework, our approach allows both clusters to carry large masses. We derive the cross section for the production of two such clusters and show that it exhibits geometric scaling. Testing this scaling behaviour against data from high-energy colliders such as the LHC will be a crucial step in establishing whether large Pomeron loops play a major role in high energy QCD dynamics, and in particular in the unitarization of the scattering amplitude.
