“…New Fayet-Iliopoulos terms have been recently introduced for N = 1 supergravity theories that do not require the gauging of the R-symmetry [22][23][24][25], and have been studied and developed in a series of publications [71][72][73][74][75][76][77][78]. To highlight some interesting aspects of these constructions let us mention that new type of scalar potentials can be introduced that lead to new possibilities for inflation in supergravity [24,72], but also to new possibilities regarding the vacuum structure [22,25], while the matter content of the theory is still described by standard N = 1 supermultiplets, including the FI gauge multiplet.…”

We present a new type of Fayet-Iliopoulos (FI) terms in N = 2 supergravity that do not require the gauging of the R-symmetry. We elaborate on the impact of such terms on the vacuum structure of the N = 2 theory and compare their properties with the standard Fayet-Iliopoulos terms that arise from gaugings. In particular, we show that, with the use of the new FI terms, models with a single physical N = 2 vector multiplet can be constructed that give stable de Sitter vacua.1 See for instance [3-8] for reviews.

“…The coupling to supergravity is another interesting question, in particular whether it implies the gauging of the R-symmetry. Indeed, the absence of the extra fermionic contribution associated to the standard FI term exhibiting the gauging of the R-symmetry [8] suggests that this gauging may not be necessary for the coupling to supergravity in our case.…”

We study the general deformation of N = 2 supersymmetry transformations of a vector multiplet that forms a (constant) triplet under the SU (2) R-symmetry corresponding to the magnetic dual of the triplet of the Fayet-Iliopoulos (FI) parameters. We show that in the presence of both triplets, the induced scalar potential of a vector multiplet with generic prepotential has always a minimum that realises partial breaking of N = 2 → N = 1 supersymmetry. We then consider the impact of the deformation in the Dirac-Born-Infeld (DBI) action where one supersymmetry is non-linearly realised, described by a nilpotent constraint on the deformed N = 2 chiral-chiral superfield. We show that the generic magnetic deformation induces an ordinary FI D-term along the linear supersymmetry via the theta-angle. Moreover, we argue that the resulting action differs on-shell from the standard one (DBI+FI) by fermionic contributions.

“…In particular, the real part of Z(x) is related to a breathing mode field and the imaginary part is an axion field. The kinetic term for the complex field Z was identified in [54] in equation (15). In this equation, we take a more recent standard normalization of the scalar curvature term in supergravity into account, with 1/2R as the Einstein term rather than R. Then the kinetic term of a modulus associated with the stringy wormhole becomes…”
