A new conception in describing the Drell-Yan type processes

Abstract

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 → 2 are obtained. Sub-process gb → tH − as well considered.
