TL;DR
This paper proves that in five-dimensional N=2 gauged supergravity with vector multiplets, solutions preserving exactly 3/4 of supersymmetry do not exist, using spinorial geometry techniques.
Contribution
It applies spinorial geometry methods to demonstrate the non-existence of 3/4 supersymmetric solutions in this supergravity context.
Findings
No solutions preserve exactly 3/4 supersymmetry.
Method extends previous analysis techniques.
Clarifies supersymmetry constraints in 5D supergravity.
Abstract
We examine supersymmetric solutions of N=2, D=5 gauged supergravity coupled to an arbitrary number of abelian vector multiplets using the spinorial geometry method. By making use of methods developed in hep-th/0606049 to analyse preons in type IIB supergravity, we show that there are no solutions preserving exactly 3/4 of the supersymmetry.
