Nonlinear evolution of unintegrated gluon density at large values of coupling constant

We propose an evolution equation for unintegrated gluon densities that is valid for large values of the QCD coupling constant (alpha) over bar (s). Our approach is based on the linear resummation model introduced by Stasto. 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.
