Description
I will present a novel solution to the long-standing issue of obtaining de Sitter spacetimes from a pure Supergravity theory. Our model is based on the first superspace formulation of unimodular gravity, in conjunction with a (super)-Stueckelberg construction. I will then present a comparison between our model and other proposals in the literature, based on constrained superfields. Even through the approaches are very different, I will show that the two proposals converge towards the same theory, thus offering a tantalising glimpse of a more general framework.
