  If gravity becomes strong at the TeV scale, we may have the chance to produce
black holes at particle colliders. In this paper we study some experimental
signatures of black hole production in TeV-gravity theories. In contrast with
the usual lore, we show that the black hole energy loss in the bulk during the
Hawking evaporation phase may be of the same order of the energy radiated into
the brane. We investigate in detail the multiplicity of the decay products of
black hole evaporation. We find that the number of particles produced during
the evaporation phase is significantly lower than the average multiplicity
which has been used in the past literature.
