Abstract

We include resummation of large transverse logarithms into the next-to-leading order Balitsky-Kovchegov equation. The resummed NLO evolution equation is shown to be stable, the evolution speed being significantly reduced by higher order corrections. The contributions from α_s² terms that are not enhanced by large logarithms are found to be numerically important close to phenomenologically relevant initial conditions.
