It is a remarkable fact that in brane-world theories the true scale M * of quantum gravity may be substantially lower than the traditional Planck scale M pl , possibly approaching the TeV scale, and this radical departure from the standard picture is not excluded @1 #~ for earlier works on brane theories, see @2#!. This observation has naturally excited a large amount of activity investigating both the structure of these theories and their experimental signals @3#. One of the most striking consequences of lowering the Planck scale to the TeV region is that the properties of small black holes are substantially altered @4#. A black hole of given mass M is now much lighter, larger, and colder than a usual black hole of the same mass, provided only that the Schwarschild radius r H of the black hole ~BH! is smaller than the size of the extra dimensions r H,R. In this limit, the black hole is well described as a (4 1n)-dimensional black hole centered on the brane, but extending out into the n extra dimensions. The horizon radius r H of such a black hole is @4,5#
