In this chapter we want to discuss some aspects of images = 1 supergravity that are important for applications. This will also improve our understanding of the structure of supergravity theories.

19.1   Supersymmetry breaking and the super-BEH effect

We discussed supersymmetry breaking in global supersymmetry in Sec. 14.5. The main result is that supersymmetry is broken when at least one auxiliary field does not vanish at the minimum of the potential. Since the potential is positive definite, this implies that the vacuum energy is positive. A massless ...
