Description
This talk reviews recent work done in collaboration with H. Jang on recently discovered new supergravity actions. Besides the standard ones, they contain new terms that become singular when auxiliary fields vanish. Constraints on the magnitude of such new terms are found by standard low-energy effective field theory consistency checks. After discussing those constraints I will present a realization of supergravity inflation that uses the new Kaehler-invariant Fayet-Iliopoulos term recently introduced by Antoniadis, Chatrabhuti, Isono and Knoops.
