Abstract

A natural combined model of the Kerr spinning particle and superparticle is obtained leading to a non-trivial super black hole solution. By analogue with complex structure of the Kerr solution we perform a supershift on the Kerr geometry, and then select a "body"-submanifold of superspace that yields a non-trivial supergeneralization of the Kerr metric with a nonlinear realization of (2,0)-supersymmetry. For the known parameters of spinning particles this "black hole" is to be in a specific state without horizons and very far from extreme. The naked Kerr singular ring has to be hidden inside a rotating superconducting disk, built of a supermultiplet of matter fields. Stringy wave excitations of the Kerr singular ring (traveling waves) yield an extra axial singular line modulated by de Broglie periodicity.
