Pomeron Fans for Finite Nuclei

详细

In perturbative QCD, we study a set of pomeron fan diagrams propagating from a projectile to A nucleons in the nucleus target for finite A and investigate its behavior at large A and convergence as A→∞. We find convergence for only very small values of the coupling constant αs, much smaller than the commonly assumed values. We compare the results with the solution of the Balitski–Kovchegov equation.
