Abstract
We propose an evolution equation for unintegrated gluon densities that is valid for large values of the QCD coupling constant ${\overline{\ensuremath{\alpha}}}_{s}$. Our approach is based on the linear resummation model introduced by Stas\ifmmode \acute{}\else \'{}\fi{}to. We generalize the model including a nonlinear term in the diffusive regime. The validity of the diffusive evolution at strong coupling is supported by the AdS/CFT consideration, as well as perturbative arguments. We solve the evolution equation numerically and extract the saturation scale, which we compare with the weak coupling counterpart.
