Three Lectures on the Physics of Small x and High Gluon Density

TL;DR

This paper discusses the physics of small x and high gluon density, emphasizing their importance for understanding high energy hadronic processes and the potential for first principles QCD calculations.

Contribution

It introduces a framework for understanding high gluon density effects at small x and their implications for high energy asymptotics in QCD.

Findings

High gluon density influences small x physics significantly.

Understanding this can lead to first principles calculations of high energy asymptotics.

Provides theoretical insights into the behavior of hadronic processes at high energies.

Abstract

In these lectures, I shall discuss small x physics and the consequences of high gluon density which arises as x decreases. I argue that an understanding of this problem would lead to knowledge of the high energy asymptotics of hadronic processes. The high gluon density should allow a first principles computation of these asymptotics from QCD.
