The Gravity Dual of Softly Broken N=1 Super Yang-Mills

TL;DR

This paper explores how adding a gaugino mass term to the supergravity dual of N=1 super Yang-Mills lifts the vacuum degeneracy, providing insights into supersymmetry breaking effects in gauge/gravity duality.

Contribution

It introduces a class of non-supersymmetric deformations of the Maldacena-Nunez solutions that incorporate both mass and condensate effects, advancing the understanding of supersymmetry breaking in holographic models.

Findings

Vacuum energy calculations show degeneracy lifting due to mass term

Deformations interpreted as including both mass and condensate

N-fold vacuum degeneracy is broken by supersymmetry breaking

Abstract

Starting from the Maldacena-Nunez supergravity dual of N=1 super Yang-Mills theory we study the inclusion of a supersymmetry breaking gaugino mass term. We consider a class of non supersymmetric deformations of the MN solutions which have been recently proposed in the literature. We show that they can be interpreted as corresponding to the inclusion of both a mass and a condensate. We calculate the vacuum energy of the supergravity solutions showing that the N-fold vacuum degeneracy of the N=1 theory is lifted by the inclusion of a mass term.
