Membranes and Fivebranes with Lower Supersymmetry and their AdS Supergravity Duals

TL;DR

This paper explores superconformal field theories with reduced supersymmetry in three and six dimensions, proposing their dual descriptions via specific AdS supergravity models derived from M-theory branes at orbifold singularities.

Contribution

It identifies the supergravity duals for 3D and 6D superconformal theories with eight supercharges, expanding the understanding of gauge/gravity correspondence in lower supersymmetry contexts.

Findings

Superconformal theories with eight supercharges exist in 3D and 6D.

Corresponding N=4 and N=2 supergravity duals are proposed in AdS_4 and AdS_7.

Characteristics of the relevant gauged supergravities are discussed.

Abstract

We consider superconformal field theories in three and six dimensions with eight supercharges which can be realized on the world-volume of M-theory branes sitting at orbifold singularities. We find that they should admit a N=4 and N=2 supergravity dual in AdS_4 and AdS_7, respectively. We discuss the characteristics of the corresponding gauged supergravities.
