Axion-like particles from primordial black hole evaporation and their detection in neutrino experiments (arXiv:2208.02696v2 [hep-ph]).
The authors study the energetic photoelectron signatures produced by the ALPs that evaporated from the PBH. The photoelectron signatures can be detected by underground neutrino detectors such as Super-K and Hyper-K. Authors then make constraints on the axion-photon coupling constant, axion-nEDM coupling constant, and f_{DM} for small PBH mass.
