Atom made from charged elementary black hole - art. no. 084010

It is believed that there may have been a large number of black holes forme d in the very early universe. These would have quantized masses. A charged "elementary black hole" (with the minimum possible mass) can capture electr ons, protons, and other charged particles to form a "black hole atom." We f ind the spectrum of such an object with a view to laboratory and astronomic al observations of them. There is no limit to the charge of the black hole, which gives us the possibility of observing Z>137 bound states and transit ions at a lower continuum. Negatively charged black holes can capture proto ns. For Z>1, the orbiting protons will coalesce to form a nucleus (after be ta decay of some protons to neutrons), with a stability curve different fro m that of free nuclei. In this system there is also the distinct possibilit y of single quark capture. This leads to the formation of a colored black h ole that plays the role of an extremely heavy quark interacting strongly wi th the other two quarks. Finally we consider atoms formed with much larger black holes.
