Unlocking the Axion-Dilaton in 5D Supergravity

Understand

We revisit supersymmetric solutions to five dimensional ungauged N=1 supergravity with dynamic hypermultiplets.

• In particular we focus on a truncation to the axion-dilaton contained in the universal hypermultiplet.
• The relevant solutions are fibrations over a four-dimensional Kahler base with a holomorphic axion-dilaton.
• We focus on solutions with additional symmetries and classify Killing vectors which preserve the additional structure imposed by supersymmetry; in particular we extend the existing classification of solutions with a space-like U(1) isometry to the case where the Killing vector is rotational.
