We propose a decay signature for non-thermal small black holes with masses in the TeV range which can be discovered by neutrino observatories. The black holes would result due to the impact between ultra high energy neutrinos with nuclei in water or ice and decay instantaneously. They could be produced if the Planck scale is in the few TeV region and the highly energetic fluxes are large enough. Having masses close to the Planck scale, the typical decay mode for these black holes is into two particles emitted back-to-back. For a certain range of angles between the emitted particles and the center of mass direction of motion, it is possible for the detectors to measure separate muons having specific energies and their trajectories oriented at a large enough angle to prove that they are the result of a back-to-back decay event.
Cosmological Neutrino Signatures for Grand Unification Scale Physics
超越标准模型的物理学可能意味着具有大统一尺度能量的粒子的宇宙学产生。在100 eV [10**（20）eV]以上观测到的宇宙射线可能是来自这种过程的核子和伽马射线。使用一个新的粒子传播代码，我们计算的中微子通量预测的情况下，如果与观测到的宇宙射线通量和宇宙的伽马射线背景在1-10 GeV的一致性是必需的。建议km**3规模的中微子观测站可检测的通量水平是允许的这些限制。如果中微子通量超过1 EeV，那么中微子天文学就可以探测到大统一尺度的物理学。
