Dark energy in modified supergravity

Abstract

We propose a supersymmetric extension of the dynamical dark energy function and the scalar (super)potential in $F(\mathcal{R})$ supergravity. Our model is viable in the Einstein approximation, and also has an analytic (regular) scalar potential. The hidden sector responsible for spontaneous supersymmetry breaking is also given.
