String Theory and Quark Confinement

TL;DR

Findings

Proposes new tests for gauge-string equivalence.

Analyzes the role of zigzag symmetry in confining strings.

Discusses the importance of loop equations and renormalization group in string confinement.

Abstract

This article is based on a talk given at the ``Strings'97'' conference. It discusses the search for the universality class of confining strings. The key ingredients include the loop equations, the zigzag symmetry, the non-linear renormalization group. Some new tests for the equivalence between gauge fields and strings are proposed.
