Contribution
It provides a general method for embedding inflationary models into minimal supergravity with a single superfield, highlighting the tunability of supersymmetry breaking.
Findings
All inflationary models can be embedded in minimal supergravity.
Supersymmetry breaking is independently tunable.
Examples consistent with Planck data are presented.
Abstract
We prove that all inflationary models, including those with dark energy after the end of inflation, can be embedded in minimal supergravity with a single chiral superfield. Moreover, the amount of supersymmetry breaking is independently tunable due to a degeneracy in the choice for the superpotential. The inflaton is a scalar partner of the Goldstino in this set-up. We illustrate our general procedure with two examples that are favoured by the Planck data.
