Moduli stabilization with Fayet-Iliopoulos uplift
In the recent years, phenomenological models of moduli stabilization were proposed, where the dynamics of the stabilization is essentially supersymmetric, whereas an O’Rafearthaigh supersymmetry breaking sector is responsible for the ”uplift” of the cosmological constant to zero. We investigate the case where the uplift is provided by a Fayet-Iliopoulos sector. We find that in this case the mod...
متن کاملFayet-Iliopoulos Potentials fromFour-Folds
We show how certain non-perturbative superpotentials W̃ (Σ), which are the two-dimensional analogs of the Seiberg-Witten prepotential in 4d, can be computed via geometric engineering from 4-folds. We analyze an explicit example for which the relevant compact geometry of the 4-fold is given by IP fibered over IP. In the field theory limit, this gives an effective U(1) gauge theory with N = (2, 2)...
متن کاملFayet-Iliopoulos Couplings, and Flux Vacua
We review the subject of Kähler anomalies in gauged supergravity, emphasizing that field equations are inconsistent when the Kähler potential is non-invariant under gauge transformations or when there are elementary Fayet-Iliopoulos couplings. Flux vacua solutions of string theory with gauged U(1) shift symmetries appear to avoid this problem. The major new result is that the Kähler anomaly inv...
متن کاملFayet - Iliopoulos D terms in string theory
One loop scalar masses induced by Fayet-Ilipoulos D terms in string theory .are calculated directly in the heterotic string theory for an arbitrary compactification which preserves space-time supersymmetry at the string tree level. The result is shown to be a total derivative in the moduli space of a torus with two punctures, and hence receives contribution only from the boundary of this moduli...
متن کاملFayet-Iliopoulos Terms in 5D Orbifold Supergravity
We discuss a locally supersymmetric formulation for the boundary Fayet-Iliopoulos (FI) terms in 5-dimensional U(1) gauge theory on S/Z2, using the four-form multiplier mechanism to introduce the necessary Z2-odd FI coefficient. The physical consequence of the boundary FI terms is studied within the full supergravity framework. For both models giving a flat and a warped spacetime geometry, the o...
