The BFKL Pomeron calculus: Summing enhanced diagrams

Research output: Contribution to journalArticlepeer-review

Abstract

The goal of this paper is to sum over a class of enhanced diagrams, and derive a new Pomeron Green function. It is found that this sum gives the Pomeron contribution to the scattering amplitude that decreases with energy. In other words, we found that the total cross section of two colourless dipoles of small but equal sizes, falls down at high energies.
