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 ∼1–3Mf 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.
Highlights
Recent calculations applying statistical mechanics indicate that in a setting with compactified large extra dimensions a black hole might evolve into astable state with mass close to the new fundamental scale Mf
Additional processes had to be expected in high-energy collisions [12]: production of real and virtual gravitons [13,14,15,16,17] and the creation of black holes at energies that can be achieved at colliders in the near future
The general notion is that a small black hole stops evaporating particles when its mass approaches the Planck scale, resulting in the exciting possibility of forming astable relic
Summary
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. The general notion is that a small black hole stops evaporating particles when its mass approaches the Planck scale, resulting in the exciting possibility of forming a (quasi-)stable relic. The quantisation of the radiation can lead to black hole relics of masses around 1-3 TeV with small electric charge.
