If the fundamental Planck scale is of order of a TeV, as is the case in some extra-dimension scenarios, future hadron colliders such as the CERN Large Hadron Collider will be black hole factories. The nonperturbative process of black hole formation and decay by Hawking evaporation gives rise to spectacular events with up to many dozens of relatively hard jets and leptons with a characteristic ratio of hadronic to leptonic activity of roughly 5:1. The total transverse energy of such events is typically a sizable fraction of the beam energy. Perturbative hard scattering processes at energies well above the Planck scale are cloaked behind a horizon, thus limiting the ability to probe short distances. The high energy black hole cross section grows with energy at a rate determined by the dimensionality and geometry of the extra dimensions. This dependence therefore probes the extra dimensions at distances larger than the Planck scale.

• UV-completion by classicalization (2010, background): “However, the situation could be very different if gravity becomes strong at the TeV scale [23], since black holes could be formed in proton collisions at the LHC [24–28].”
• Rotating black holes at future colliders: Greybody factors for brane fields (2002, background): “They have explicitly provided a solution of the five-dimensional vacuum Einstein equation, which represents the stationary rotating black ring (homeomorphic to S1 × S2).”
• Evidence for a sublattice weak gravity conjecture (2016, background): “This larger energy scale is the higherdimensional Planck scale, which determines the energy at which generic scattering processes are expected to form (higher-dimensional) black holes and short distance physics gives way to Asymptotic Darkness [40–42].”

• Classical black hole production in high-energy collisions (2002, background): “It has been argued that at high energies black hole production has a good semiclassical description[6, 7], since in such cases a horizon should form in a region where the curvature is weak and quantum gravity effects are small.”
