New Kähler invariant Fayet–Iliopoulos terms in supergravity and cosmological applications
2020
European Physical Journal C: Particles and Fields
Recently, a new type of constant Fayet-Iliopoulos (FI) terms was introduced in N = 1 supergravity, which do not require the gauging of the R-symmetry. We revisit and generalise these constructions, building a new class of Kähler invariant FI terms parametrised by a function of the gravitino mass as functional of the chiral superfields, which is then used to describe new models of inflation. They are based on a no-scale supergravity model of the inflaton chiral multiplet, supplemented by an
