Linearly Polarized Gluon Density at Low x
Abstract
Based on a solution of DGLAP evolution equations at small values of Bjorken variable x, a simple analytic approximation for the perturbative part of so-called linearly polarized gluon density $$h_{1}^{{ \bot g}}$$ (x, $$b_{t}^{2}$$ , Q2) is obtained at the leading order of perturbation theory. We demonstrate that derived expressions reproduce the main features of complicated numerical calculations performed by the parametrization groups.
