Abstract

N=8 supergravity is currently at the center of many investigations because of its possible ultraviolet finiteness. I will present some new results on its spontaneously broken version. I will prove that all models with N=0 Minkowski vacua are finite at 1-loop. I will also discuss a new mechanism to study the classical vacua, show that there are many more deformations than previously expected and that from a stringy perspective broken N=8 supergravity exhibits a moduli space with some intriguing features.
