It has been argued that neutrinos originating from ultrahigh energy cosmic rays can produce black holes deep in the atmosphere in models with TeV-scale quantum gravity. Such black-hole events could be observed at the Auger Observatory. However, any phenomenologically viable model with a low scale of quantum gravity must explain how to preserve protons from rapid decay. We argue that the suppression of proton decay will also suppress lepton-nucleon scattering and hence black-hole production by scattering of ultrahigh energy cosmic ray neutrinos in the atmosphere. We discuss explicitly the split fermion solution to the problem of fast proton decay.
有人认为，在具有 TeV 尺度量子引力的模型中，源自超高能宇宙射线的中微子可在大气深处产生黑洞。此类黑洞事件可在奥格天文台观测到。然而，任何具有低尺度量子引力且在现象学上可行的模型都必须解释如何保护质子免于快速衰变。我们认为，对质子衰变的抑制也会抑制轻子 - 核子散射，从而抑制超高能宇宙射线中微子在大气中的散射产生黑洞。我们明确讨论了快速质子衰变问题的分裂费米子解决方案。
