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-c-fold vacuum degeneracy of the N = 1 theory is lifted by the inclusion of a mass term.

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-c-fold vacuum degeneracy of the N = 1 theory is lifted by the inclusion of a mass term.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
