BFKL Pomeron calculus: Nucleus–nucleus scattering

In this paper the action of the BFKL Pomeron calculus is rewritten in momentum representation, and the equations of motion for nucleus–nucleus collisions are derived, in this representation. We found the semiclassical solutions to these equations, outside of the saturation domain. Inside this domain these equations reduce to the set of delay differential equations, and their asymptotic solutions are derived.
