如果基本普朗克尺度是TeV的量级，就像某些额外维度的情况一样，未来的强子对撞机，如欧洲核子研究中心的大型强子对撞机，将是黑洞工厂。霍金蒸发导致的黑洞形成和衰变的非微扰过程产生了壮观的事件，其中有数十个相对较硬的喷流和轻子，强子与轻子活动的特征比例约为5：1。这种事件的总横向能量通常是束能量的相当大的一部分。能量远高于普朗克尺度的微扰硬散射过程隐藏在视界后面，从而限制了探测短距离的能力。高能黑洞的横截面随着能量的增加而增长，其增长速度由额外维度的维度和几何形状决定。因此，这种依赖关系探测了距离大于普朗克尺度的额外维度。
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.
