Infrared gluons, intrinsic transverse momentum and rising total cross-sections

TL;DR

This paper explores how the infrared behavior of soft gluon resummation influences observable phenomena like intrinsic transverse momentum and the growth of total cross-sections at high energies.

Contribution

It establishes a connection between infrared gluon dynamics and measurable quantities such as transverse momentum and total cross-section rise.

Findings

Infrared gluon effects impact intrinsic transverse momentum.

Infrared behavior influences the energy dependence of total cross-sections.

Resummation techniques relate soft gluon dynamics to high-energy observables.

Abstract

We discuss the infrared limit for soft gluon kt-resummation and relate it to physical observables such as the intrinsic transverse momentum and the high energy limit of total cross-sections.
