Using superconformal methods we derive an explicit de Sitter supergravity action invariant under spontaneously broken local N = 1 supersymmetry. The supergravity multiplet interacts with a nilpotent Goldstino multiplet. We present a complete locally supersymmetric action including the graviton and the fermionic fields, gravitino and Goldstino, no scalars. In the global limit when the supergravity multiplet decouples, our action reproduces the Volkov-Akulov theory. In the unitary gauge where the Goldstino vanishes we recover pure supergravity with the positive cosmological constant. The classical equations of motion, with all fermions vanishing, have a maximally symmetric solution: de Sitter space.

The Landscape, the Swampland and the Era of Precision Cosmology (2018, background): “The new construction of local supergravity with dS vacua [30, 31] has demonstrated that one can evade the no-go theorem [35] and construct dS vacua even in pure supergravity without scalar fields by including a nonlinearly realized supersymmetry.”
Low-dimensional de Sitter quantum gravity (2019, background): “We expect SUSY to be broken, as in [117], although perhaps not so badly.”
