Three-forms and Fayet-Iliopoulos terms in supergravity: scanning Planck mass and BPS domain walls
Abstract We embed a new three-form vector multiplet in N $$ \mathcal{N} $$ = 1 supergravity and we show that it can be used to generate dynamically the Hilbert-Einstein term. We then recast the theory into the standard Freedman model and we argue that a pure Fayet-Iliopoulos term is in tension with...

Summary: | Abstract We embed a new three-form vector multiplet in N $$ \mathcal{N} $$ = 1 supergravity and we show that it can be used to generate dynamically the Hilbert-Einstein term. We then recast the theory into the standard Freedman model and we argue that a pure Fayet-Iliopoulos term is in tension with the Weak Gravity Conjecture. Finally, we couple the three-form to a super-membrane and study BPS domain walls within matter-coupled supergravity. In these models, the Planck mass takes different values on the domain wall sides. |
