Abstract:
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 $A\to\infty$. We find convergence for only very small values of the coupling constant $\alpha_\mathrm{s}$, much smaller than the commonly assumed values. We compare the results with the solution of the Balitski–Kovchegov equation.
Keywords:strong interaction, quantum chromodynamics, pomeron, fan diagram.
