On the $k_{\perp}$ dependent gluon density in hadrons and the photon
Abstract
Description
The $k_{\perp}$ dependent gluon distribution for protons, pions,and photons is calculated accounting for the resummation of small~$x$ effects due to the Lipatov equation. It is represented by a convolution of a gluon density in the collinear limit and a universal function ${\cal G}(x,k^2,μ)$ for which an analytic expression is derived.
