Camouflaged Supersymmetry

TL;DR

This paper uncovers a surprising phenomenon where certain supersymmetric solutions in N=8 supergravity are not supersymmetric within any N=2 truncation, suggesting larger families of microstates than previously known.

Contribution

It reveals that some supersymmetric solutions can exist outside the supersymmetric truncations, expanding the understanding of black hole microstates and supersymmetry.

Findings

Existence of solutions supersymmetric in N=8 but not in N=2 truncations

Potential for larger families of supersymmetric black rings and microstates

Connection between flux compactifications and black hole microstates

Abstract

We establish a relation between certain classes of flux compactifications and certain families of black hole microstate solutions. This connection reveals a rather unexpected result: there exist supersymmetric solutions of N=8 supergravity that live inside many N=2 truncations, but are not supersymmetric inside any of them. If this phenomenon is generic, it indicates the possible existence of much larger families of supersymmetric black rings and black hole microstates than previously thought.
