Particle dynamics near extreme Kerr throat and supersymmetry

Understand

The extreme Kerr throat solution is believed to be non-supersymmetric.

• However, its isometry group SO(2,1) x U(1) matches precisely the bosonic subgroup of N=2 superconformal group in one dimension.
• In this paper we construct N=2 supersymmetric extension of a massive particle moving near the horizon of the extreme Kerr black hole.
• Bosonic conserved charges are related to Killing vectors in a conventional way.
