Destroying Kaluza-Klein black holes
INTERNATIONAL JOURNAL OF MODERN PHYSICS D(2023)
Abstract
We investigate the destroying of charged and rotating black holes in Einstein-Maxwell-(dilaton) theory. We show that a test particle with some appropriate properties in the black hole background can turn the black hole into a naked singularity. In this work, we neglect the self-force, self-energy and radiative effects as considered by some others in literature. As the result, we are able to show that the Kaluza-Klein black holes can be destroyed by the test particle. Furthermore, we consider the overspinning of the black hole by a neutral test scalar field.
