A Non--Supersymmetric Dyonic Extreme Reissner--Nordstr\"{o}m Black Hole

TL;DR

This paper introduces a non-supersymmetric dyonic embedding of the extreme Reissner-Nordström black hole within $N=4$ and $N=8$ supergravity theories, expanding understanding of black hole solutions beyond supersymmetric cases.

Contribution

It provides the first explicit construction of a non-supersymmetric dyonic extreme Reissner-Nordström black hole in these supergravity models.

Findings

Demonstrates a consistent embedding in $N=4$ and $N=8$ supergravity.

Breaks all supersymmetries in the embedding.

Expands the class of known black hole solutions.

Abstract

We present a dyonic embedding of the extreme Reissner-Nordstr\"om black hole in $N=4$ and $N=8$ supergravity that breaks all supersymmetries.
