“…[ 14 ] It was recently noticed that this model is dual under electromagnetic duality to a supergravity theory with deformed supersymmetry, or equivalently to a magnetic Fayet‐Iliopoulos term. [ 15 ]…”

We propose a generalisation of the Weak Gravity Conjecture in de Sitter space by studying charged black‐holes and comparing the gravitational and an abelian gauge forces. Using the same condition as in flat space, namely the absence of black‐hole remnants, one finds that for a given mass m there should be a state with a charge q bigger than a minimal value qnormalminfalse(m,lfalse), depending on the mass and the de Sitter radius l, in Planck units. In the large radius flat space limit (large l), qnormalmin→m leading to the known result q>m/2, while in the highly curved case (small l) qmin behaves as ml. We also discuss the example of the gauged R‐symmetry in N=1 supergravity.

“…The other examples of the D-term based on the alternative FI terms [14,15] can be found in Refs. [13,38,39,40,41]. Those FI terms provide a tunable positive cosmological constant or dS uplifting of the vacuum after inflation [12,16,17,42].…”

Generalized dilaton–axion models of inflation, de Sitter vacua and spontaneous SUSY breaking in supergravity

We propose the unified models of cosmological inflation, spontaneous SUSY breaking, and the dark energy (de Sitter vacuum) in N = 1 supergravity with the dilaton-axion chiral superfield T in the presence of an N = 1 vector multiplet with the alternative Fayet-Iliopoulos term. By using the Kähler potential as K = −α log(T + T ) and the superpotential as a sum of a constant and a linear term, we find that viable inflation is possible for 3 ≤ α ≤ α max where α max ≈ 7.235. Observations of the amplitude of primordial scalar perturbations fix the SUSY breaking scale in our models as high as 10 13 GeV. In the case of α > 3 the axion gets the tree-level (non-tachyonic) mass comparable to the inflaton mass. 1 yermek.a@chula.ac.th

“…Finally, we mention a possible connection to extended supersymmetry and supergravity. Some alternative FI terms were recently found in N = 2 supergravity [45]. The N = 2 supersymmetric extensions of the BI theory both in superspace and via non-linear realizations also exist [46,47,48,49,50].…”

Minimal Starobinsky supergravity coupled to a dilaton-axion superfield

The minimal Starobinsky supergravity with inflaton (scalaron) and goldstino in a massive vector supermultiplet is coupled to the dilaton-axion chiral superfield with the no-scale Kähler potential and a superpotential. The Kachru-Kallosh-Linde-Trivedi (KKLT)-type superpotential with a constant term is used to stabilize dilaton and axion during inflation, but it is shown to lead to an instability. The instability is cured by adding the alternative Fayet-Iliopoulos (FI) term that does not lead to the gauged R-symmetry. Other stabilization mechanisms, based on the Wess-Zumino (WZ)-type superpotential, are also studied in the presence of the FI term. A possible connection to the D3-brane models is briefly discussed too.
