Evolution of gluon TMDs from small to moderate x

Abstract

Recently we obtained an evolution equation of gluon TMDs, which addresses a problem of unification of different kinematic regimes. It describes evolution in the whole range of Bjorken $x_B$ and the whole range of transverse momentum $k_{\perp }$. In this notes I study different limits of this evolution equation and show how it yields several well-known and some previously unknown results.
