Quantum Black Holes As Elementary Particles

Abstract

Are black holes elementary particles? Are they fermions or bosons? We investigate the remarkable possibility that quantum black holes are the smallest and heaviest elementary particles. We are able to construct various fundamental quantum black holes: the spin-0, spin 1/2, spin-1, and the Planck-charge cases, using the results in general relativity. Quantum black holes in the neighborhood of the Galaxy could resolve the paradox posed by the Greisen-Zatsepin-Kuzmin limit on the energy of cosmic rays from distant sources. They could also play a role as dark matter in cosmology.

Comments

Quantum black holes with a typical mass of 10^{-5} gm are semiclassical objects. Like a heavy nucleus of an atom, they may subject to the rules of quantum mechanics but not necessarily to the rules of quantum field theory. 12 pages
