  A set of evolution equations for correlators of densities of quark and gluons
is considered. Approximate solutions is obtained in frames of gluon and quark
dominance. A new formulation of the cross sections of Drell-Yan process is
suggested. Differential cross sections for the QCD sub-processes of type $2 \to
2$ are obtained. Sub-process $g b\to tH^-$ as well considered.
