标题： Black Hole Relics in Large Extra Dimensions

摘要： 最近应用统计力学的计算表明，在具有大紧致额外维的环境下，黑洞可能会演化成一个（准）稳定状态，其质量接近新的基本尺度$M_f$。 在存在额外维拓扑的情况下，黑洞及其遗迹可能在大型强子对撞机（LHC）上产生。 在这个能量范围内，由于能量守恒和量子效应，霍金的蒸发场景会发生改变。 我们重新分析了小黑洞的蒸发过程，包括由于黑洞有限表面导致的辐射量子化。 结果发现，会形成可观测的稳定黑洞遗迹，其质量为$\sim 1-3 M_f$，这些遗迹可以通过延迟的单一喷注进行识别，该喷注会对遗迹施加相应的高动量冲击，并通过电离等方式进行识别，例如在TPC中。 显示英文摘要

摘要： 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 $M_f$. 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 $\sim 1-3 M_f$ 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.
