Duality of Non-Supersymmetric Large N Gauge Theories

TL;DR

This paper constructs and analyzes non-supersymmetric gauge theory dual pairs derived from supersymmetric dualities using orbifold projections in the large N limit, revealing potential non-supersymmetric dualities.

Contribution

It introduces a method to generate non-supersymmetric dual pairs from supersymmetric theories via orbifold projection in the large N limit.

Findings

Non-supersymmetric dual pairs remain dual after orbifold projection.

The resulting theories contain chiral fermions and massless scalars.

The approach extends duality concepts to non-supersymmetric contexts.

Abstract

Starting from Seiberg's electric-magnetic duality for supersymmetric QCD, we construct dual pairs of non-supersymmetric gauge theories. This is accomplished by first taking the large N limit of supersymmetric QCD and its dual partner and then performing a special ``orbifold projection'' recently introduced by Kachru and Silverstein. We argue that in the large N limit the two projected theories remain dual. The non-supersymmetric gauge theories which can be studied in this fashion have non-supersymmetric field content, chiral fermions and exactly massless scalar matter.
