Towards a complete classification of 6D supergravities
Yuta Hamada, Gregory J. Loges
The constraints arising from anomaly cancellation are particular strong for chiral theories in six dimensions. We make progress towards a complete classification of 6D supergraviti…
A 10d construction of Euclidean axion wormholes in flat and AdS space
Gregory J. Loges, Gary Shiu, Thomas Van Riet
Euclidean wormhole geometries sourced by axions and dilatons are puzzling objects in quantum gravity. From one side of the wormhole to the other, the scalar fields traverse a few P…
On (Scalar QED) Gravitational Positivity Bounds
Yuta Hamada, Rinto Kuramochi, Gregory J. Loges +1
We study positivity bounds in the presence of gravity. We first review the gravitational positivity bound at the tree-level, where it is known that a certain amount of negativity i…
