Dynamical Supersymmetry Breaking in Supergravity Theories

In rigid supersymmetry, generic models of dynamical supersymmetry breaking contain a light Goldstone boson, called the R axion. We show that supergravity effects explicitly break the R symmetry and give mass to the R axion. For visible and renormalizable hidden sector models, the massive R axion is free from astrophys-ical and cosmological problems. For nonrenormalizable hidden sector models, t...

The supergravity dual of a theory with dynamical supersymmetry breaking

We study the large N limit of a little string theory that reduces in the IR to U(N) N = 1 supersymmetric Yang-Mills with Chern Simons coupling k. Witten has shown that this field theory preserves supersymmetry if k ≥ N/2 and he conjectured that it breaks supersymmetry if k < N/2. We find a non-singular solution that describes the k = N/2 case, which is confining. We argue that increasing k corr...

Supersymmetry Breaking with Vanishing F -terms in Supergravity Theories

In conventional supergravity theories, supersymmetry is broken by a non-zero F -term, and the cosmological constant is fine tuned to zero by a constant in the superpotential W . We discuss a class of supergravity theories with vanishing F -terms but 〈W 〉 6 = 0 being generated dynamically. The cosmological constant is assumed to be cancelled by a non-zero D-term. In this scenario the gravity-med...

Supersymmetry, supergravity, superspace and BRST symmetry in a simple model

In these lectures we shall introduce rigid supersymmetry, supergravity (which is the gauge theory of supersymmetry) and superspace, and apply the results to BRST quantization. We assume that the reader has never studied these topics. For readers who want to read more about these “super” subjects, we give a few references at the end of this contribution, but the whole point of these lectures is ...

Pure spinor equations to lift gauged supergravity

We rewrite the equations for ten-dimensional supersymmetry in a way formally identical to a necessary and sufficient G-structure system in N = 2 gauged supergravity, where all four-dimensional quantities are replaced by combinations of pure spinors and fluxes in the internal space. This provides a way to look for lifts of BPS solutions without having to reduce or even rewrite the ten-dimensiona...
