"Black Holes at Future Colliders and Beyond"
If the scale of quantum gravity is as low as a TeV, as was proposed by
Arkani-Hamed, Dimopoulos, and Dvali a few years ago, one of the most
dramatic manifestation of this fact would be copious production of
miniature black holes at the CERN's LHC accelerator, qualifying the
latter as black-hole factories. These rapidly evaporating black holes
could serve as sensitive probes of quantum gravity effects, topology of
extra dimensions, and as a laboratory to produce new particles with the
mass ~100 GeV. I'll discuss the black hole production and decay
mechanisms at future colliders and the opportunities of cosmic ray
detectors in observing black holes in ultra-high-energy cosmic ray
collisions. Using the Higgs boson as an example, I'll demonstrate that
it can be found in the decays of black holes as early as in the first
hour of operation of the LHC, even with incomplete detectors.
