Abstract
- In the context of dynamical breaking of local supersymmetry (supergravity), including the Deser-Zumino super-Higgs effect, for the simple but quite representative cases of N = 1, D = 4 supergravity, we discuss the emergence of Starobinsky-type inflation, due to quantum corrections in the effective action arising from integrating out gravitino fields in their massive phase. This type of inflation may occur after a first-stage small-field inflation that characterizes models near the origin of the one-loop effective potential, and it may occur at the nontrivial minima of the latter. Phenomenologically realistic scenarios, compatible with the Planck data, may be expected for the conformai supergravity variants of the basic model. [ABSTRACT FROM AUTHOR]
