Abstract
We present a direct perturbative QCD calculation of the gluon distribution in nucleons as a QCD radiative effect. We assume that the only infrared regulator is the nucleon's radius which emerges as a natural cutoff. A technique is introduced which allows constructing the glue step by step keeping a careful balance of valence, gluons and sea and obeying all constraints. The absolute normalization and shape of the calculated gluon distribution are in good agreement with the experimental determinations.
