Starobinsky-like inflation in no-scale supergravity Wess-Zumino model with Polonyi term

Abstract

We propose a simple modification of the no-scale supergravity Wess-Zumino model of Starobinsky-like inflation to include a Polonyi term in the superpotential. The purpose of this term is to provide an explicit mechanism for supersymmetry breaking at the end of inflation. We show how successful inflation can be achieved for a gravitino mass satisfying the strict upper bound m3/2 < 103 TeV, with favoured values m3/2 ≲ O(1) TeV. The model suggests that SUSY may be discovered in collider physics experiments such as the LHC or the FCC.
