Ultra-High-Energy Neutrinos from Primordial Black Holes
arXiv:2503.19227 · doi:10.1103/vnm4-7wdc
Abstract
The KM3NeT Collaboration recently announced the detection of a neutrino with energy 220 PeV. One possible source of such ultra-high-energy particles is the rapid emission of energetic Hawking radiation from a primordial black hole (PBH) near the end of its evaporation lifetime. The mass distribution for PBHs features a power-law tail for small masses; a small subset of PBHs would be undergoing late-stage evaporation today. We find that recent high-energy neutrino events detected by the IceCube and KM3NeT Collaborations, with energies , are consistent with event-rate expectations if a significant fraction of the dark matter consists of PBHs.
