On SUSY Restoration in Single-Superfield Inflationary Models of Supergravity

Understand

We study the conditions of restoring supersymmetry (SUSY) after inflation in the supergravity-based cosmological models with a single chiral superfield and a quartic stabilization term in the K\"ahler potential.

• Some new, explicit, and viable inflationary models satisfying those conditions are found.
• The inflaton's scalar superpartner is dynamically stabilized during and after inflation.
• We also demonstrate a possibility of having small and adjustable SUSY breaking with a tiny cosmological constant.
