Inflation, Gravity Mediated Supersymmetry Breaking, and de Sitter Vacua in Supergravity with a Kähler-Invariant FI Term
Hun Jang, Massimo Porrati
We use a new mechanism for generating a Fayet-Iliopoulos term in supergravity, which is not associated to an R symmetry, to construct a semi-realistic theory of slow-roll inflation…

Constraining Liberated Supergravity
Hun Jang, Massimo Porrati
Fermionic terms in a class of locally supersymmetric theories called "liberated supergravity" are nonrenormalizable interactions proportional to inverse powers of the supersymmetry…
