Abstract:
Recent calculations applying statistical mechanics indicate
that in a setting with compactified large extra
dimensions a black hole might evolve into a
(quasi-)stable state with mass close to the new fundamental
scale Mf. Black holes and therefore their relics might
be produced at the LHC in the case of
extra-dimensional topologies. In this energy regime,
Hawking's evaporation scenario is modified due to
energy conservation and quantum effects. We reanalyse
the evaporation of small black holes including
the quantisation of the emitted radiation due to the
finite surface of the black hole. It is found that
observable stable black hole relics with masses ~1-3 Mf
would form which could be identified by a
delayed single jet with a corresponding hard momentum
kick to the relic and by ionisation, e.g., in a TPC.
