Exotic Scalar States in the AdS/CFT Correspondence

TL;DR

This paper explores new supergravity solutions with non-constant scalars that break supersymmetry and exhibit confinement, providing insights into dual non-supersymmetric gauge theories via the AdS/CFT correspondence.

Contribution

It introduces a family of Type IIb supergravity solutions with non-constant dilaton and scalar fields, extending the AdS/CFT framework to non-supersymmetric, confining theories.

Findings

Solutions exhibit non-trivial dilaton profiles and confinement.

Field theories dual to these solutions are non-supersymmetric.

The models demonstrate running coupling behavior.

Abstract

We investigate a family of solutions of Type IIb supergravity which asymptotically approach AdS_5 X S^5 but contain a non-constant dilaton and volume scalar for the five-sphere. These solutions preserve an SO(1,3) X SO(6) symmetry. We discuss the solution in the context of the AdS/CFT correspondence, and we find that as well as running coupling from the nontrivial dilaton, the corresponding field theory has no supersymmetry and displays confinement at least for a certain range of parameters.
