The γ-trace anomaly of supersymmetry current in a supersymmetric gauge theory shares a superconformal anomaly multiplet with the chiral R-symmetry anomaly and the Weyl anomaly, and its holographic reproduction is a valuable test to the AdS/CFT correspondence conjecture. We investigate how the γ-trace anomaly of the supersymmetry current of N = 1 four-dimensional su-persymmetric gauge theory in ...

We study the vacuum structure of the U(N) gauge model with partially broken N = 2 supersymmetry. From the analysis of the classical vacua of this model, we point out that in addition to the ordinary N = 1 supersymmetric vacua, there are vacua with negative gauge coupling constants, which preserve another N = 1 supersymmetry. These latter vacua can be analyzed by using SUSY/non-SUSY duality whic...

If there are multiple hidden sectors which independently break supersymmetry, then the spectrum will contain multiple goldstini. In this paper, we explore the possibility that the visible sector might also break supersymmetry, giving rise to an additional pseudogoldstino. By the standard lore, visible sector supersymmetry breaking is phenomenologically excluded by the supertrace sum rule, but t...

Supersymmetry of five dimensional string solutions is examined in the context of gauged D = 5, N = 2 supergravity coupled to abelian vector multiplets. We find magnetic black strings preserving one quarter of supersymmetry and approaching the half-supersymmetric product space AdS3 × H near the event horizon. The solutions thus exhibit the phenomenon of supersymmetry enhancement near the horizon...

We find the combinations of momentum and domain-wall charges corresponding to BPS states preserving 1/4, 1/2 or 3/4 of D=4 N=1 supersymmetry, and we show how the supersymmetry algebra implies their stability. These states form the boundary of the convex cone associated with the Jordan algebra of 4 × 4 real symmetric matrices, and we explore some implications of the associated geometry. For the ...
