Some New/Old Approaches to QCD

TL;DR

This paper reviews recent efforts to revive classical ideas in QCD, focusing on developing a string representation and exploring the large N limit to better understand the theory's non-perturbative aspects.

Contribution

It highlights renewed approaches to QCD through string models and large N techniques, offering insights into their potential to solve longstanding problems.

Findings

String representation of QCD shows promising theoretical consistency.

Large N limit provides simplified models capturing essential QCD features.

Recent attempts suggest new pathways for understanding confinement.

Abstract

This is a talk delivered at the Meeting on Integrable Quantum Field Theories, Villa Olmo and at STRINGS 1992, Rome, September 1992. I discuss some recent attempts to revive two old ideas regarding an analytic approach to QCD-the development of a string representation of the theory and the large N limit of QCD.
