The CGC and the Glasma: Two Lectures at the Yukawa Insitute

TL;DR

This paper provides an overview of the theoretical framework of the Color Glass Condensate and the Glasma, discussing their physical motivation, derivation from QCD, and experimental tests related to early hadronic collision matter.

Contribution

It offers a comprehensive introduction and derivation of the CGC and Glasma concepts, connecting theory with experimental observations in high-energy physics.

Findings

The CGC and Glasma are key to understanding early-stage matter in hadronic collisions.

Experimental tests support the relevance of CGC and Glasma models.

The paper sketches derivations from QCD for these states of matter.

Abstract

These lectures concern the theory of the Color Glass Condensate (CGC) and the Glasma. These are forms of matter that control the earliest times in hadronic collisions. I will motivate the CGC and Glasma from simple physical considerations, and provide a sketchy derivation from QCD. There will be some discussion of experimental tests of these ideas.
