From Surface Roughening to QCD String Theory

TL;DR

This paper explores the connection between surface roughening phenomena and QCD string theory, discussing implications for lattice studies of quark confinement and the challenges in modeling Wilson surfaces.

Contribution

It introduces new ideas linking surface critical phenomena to QCD flux and examines issues with simple string models of Wilson surfaces.

Findings

Surface roughening relates to confining flux in QCD.

Challenges exist in modeling Wilson surfaces with simple string theories.

Implications for lattice QCD studies are discussed.

Abstract

Surface critical phenomena and the related onset of Goldstone modes represent fundamental properties of the confining flux in Quantum Chromodynamics. New ideas on surface roughening and their implications for lattice studies of quark confinement and string formation are presented. Problems with a simple string description of the large Wilson surface are discussed.
