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. Differen
tial cross sections for the QCD sub-processes of type $2 to 2$ are obtained. Sub-process $g bto tH^-$ as well considered.
