Description
One of the outstanding problems in theoretical physics is the cosmological constant problem. In the context of supersymmetry, the origin of supersymmetry breaking remains a mystery. We present a self-contained no-scale supergravity model which incorporates the Starobinsky-like inflation, an adjustable supersymmetry breaking scale $\mathcal{O}(10^{3})$ GeV, and a small positive cosmological constant (dark energy density) at a scale $\mathcal{O}(10^{-120})$. The mechanism also avoids the problem of AdS vacua, which are often found in supergravity models and are corrected a posteriori. This provides a framework which can be combined with various inflationary potentials, including the α-attractors.
