de Sitter Conjectures in N=1 Supergravity

Supergravity theories at allow to formulate the Swampland de Sitter conjectures in the complex field space of scalar components of chiral multiplets. We formulate the refined de Sitter conjecture by using the Kähler invariant ‐function and explore a class of models in the Landscape/Swampland scenari...

description Supergravity theories at allow to formulate the Swampland de Sitter conjectures in the complex field space of scalar components of chiral multiplets. We formulate the refined de Sitter conjecture by using the Kähler invariant ‐function and explore a class of models in the Landscape/Swampland scenario which obey and/or violate such conjectures. Furthermore we give a new construction of exponential potentials in supergravity. These depend on a chiral superfield with a Kähler potential parametrizing an geometry. We show that the construction allows for modifications to supergravity theories causing them to obey the de Sitter conjectures.

We formulate the de Sitter and refined de Sitter conjecture by using the K\"ahler invariant ${\cal G}$-function and explore a class of models in the Landscape/Swampland scenario which obey and/or violate such conjectures. Furthermore we give a new construction of single exponential potentials in supergravity. These depend on a chiral superfield with a K\"ahler potential parametrizing an SU(1,1)/U(1) geometry. We show that the construction allows for modifications to supergravity theories causing them to obey the de Sitter conjectures.arXiv:1912.06626CERN-TH-2019-220oai:cds.cern.ch:27045612019-12-13
