New Fayet-Iliopoulos terms in N = 2 $$ \mathcal{N}=2 $$ supergravity
Abstract We present a new type of Fayet-Iliopoulos (FI) terms in N = 2 $$ \mathcal{N}=2 $$ 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 $$ \mathcal{N}=2 $$ theory and compare their properties with the st...

| Summary: | Abstract We present a new type of Fayet-Iliopoulos (FI) terms in N = 2 $$ \mathcal{N}=2 $$ 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 $$ \mathcal{N}=2 $$ 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 $$ \mathcal{N}=2 $$ vector multiplet can be constructed that give stable de Sitter vacua. |
