A new conception in describing the Drell-Yan type processes

TL;DR

This paper introduces a new approach to describing Drell-Yan processes by developing evolution equations for parton density correlators, proposing a novel cross section formulation, and calculating differential cross sections for relevant QCD sub-processes.

Contribution

It presents a new formulation for Drell-Yan cross sections and derives differential cross sections for specific QCD sub-processes, including the $g b o tH^-$ channel.

Findings

Derived evolution equations for quark and gluon density correlators.

Proposed a new formulation for Drell-Yan cross sections.

Calculated differential cross sections for key QCD sub-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 $2 \to 2$ are obtained. Sub-process $g b\to tH^-$ as well considered.
