Gravitino and Polonyi production in supergravity

Abstract We study production of gravitino and Polonyi particles in the minimal Starobinsky-Polonyi $$\mathcal {N}=1$$ N=1 supergravity with inflaton belonging to a massive vector supermultiplet. Our model has only one free parameter given by the scale of spontaneous SUSY breaking triggered by Polony...
