Non-Perturbative Yang-Mills from Supersymmetry and Strings, Or, in the Jungles of Strong Coupling

TL;DR

This paper reviews recent progress in understanding non-perturbative aspects of Yang-Mills theory through supersymmetry and string theory, focusing on planar equivalence and strong coupling regimes.

Contribution

It discusses new insights into the non-perturbative structure of Yang-Mills theories via supersymmetric and string theoretic methods, highlighting planar equivalence.

Findings

Planar equivalence holds between supersymmetric and non-supersymmetric theories.

New non-perturbative techniques shed light on strong coupling dynamics.

Collaborative work advances understanding of gauge/string duality.

Abstract

I summarize some recent developments in the issue of planar equivalence between supersymmetric Yang-Mills theory and its orbifold/orientifold daughters. This talk is based on works carried out in collaboration with Adi Armoni, Sasha Gorsky and Gabriele Veneziano.
