SO and Sp Chern-Simons at Large N

TL;DR

This paper explores the large N limit of SO(N) and Sp(N) Chern-Simons theories on S^3, revealing their duality with topological strings on orientifolded conifolds and discussing implications for N=1 supersymmetric gauge theories.

Contribution

It identifies the closed string duals of SO(N) and Sp(N) Chern-Simons theories as topological strings on orientifolded conifold backgrounds, extending large N duality insights.

Findings

Large N duality between SO/Sp Chern-Simons and topological strings established.

Dual geometries involve orientifolds of the conifold's small resolution.

Applications to N=1 supersymmetric gauge theories discussed.

Abstract

We study the large N limit of SO(N) and Sp(N) Chern-Simons gauge theory on S^3 and identify its closed string dual as topological strings on an orientifold of the small resolution of the conifold. Applications to large N dualities for N=1 supersymmetric gauge systems in 4 dimensions are also discussed.
