The possibility of creating microscopic black holes is one of the most exciting predictions for the LHC, with potentially major consequences for our current understanding of physics.
We briefly review the theoretical motivation for micro black hole production, and our understanding of their subsequent evolution. Recent work on modelling the radiation from quantum-gravity-corrected black holes is also discussed……..
The quest for signatures of the formation of microscopic black holes in particle detectors or cosmic rays is a fascinating and ambitious program.
In this short paper we showed how their observation is connected to deeper problems concerning the very nature of quantum gravity.
We have presented both an overview of the state of the art in this ﬁeld and the latest ﬁndings based on quantum gravity improved black hole metrics.
We stress that the work in this ﬁeld is ongoing and many questions are yet to be settled. Apart from the issue of drawing a robust and widely accepted scenario for the evaporation end point, there exists a list of open problems concerning the initial phases.
For brevity we only recall that the mechanism of the collapse, the computation of the production cross section, the duration of the balding and the spin-down phases, the role of color ﬁelds, and the eﬀects of the brane tension are currently subjects of investigations.
We stress that these issues are very topical: both the LHC and the Pierre Auger Observatory are now collecting data and soon consistent explanations of experimental results will be necessary.
