Riccardo D'Auria, Silvia Vaula'
TL;DR
This paper constructs a supersymmetric de Sitter background within D=6, N=2, F(4) supergravity, revealing a new stable solution with specific symmetry properties, despite the presence of ghosts in the vector sector.
Contribution
It demonstrates the existence of a supersymmetric de Sitter background in F(4) supergravity and explicitly constructs the gauged matter coupled version.
Findings
Supersymmetric de Sitter background exists in D=6, N=2, F(4) supergravity.
The constructed model preserves the compact R-symmetry.
The theory contains ghosts in the vector sector.
Abstract
We show that there exists a supersymmetric de Sitter background for the D=6, N=2, F(4) supergravity preserving the compact R-symmetry and gauging with respect to the conventional Anti de Sitter version of the theory. We construct the gauged matter coupled F(4) de Sitter supergravity explicitly and show that it contains ghosts in the vector sector.
