Signatures of primordial black hole dark matter at DUNE and THEIA

Understand

Primordial black holes (PBHs) are a potential dark matter candidate whose masses can span over many orders of magnitude.

• If they have masses in the $10^{15}-10^{17}$ g range, they can emit sizeable fluxes of MeV neutrinos through evaporation via Hawking radiation.
• We explore the possibility of detecting light (non-)rotating PBHs with future neutrino experiments.
• We focus on two next generation facilities: the Deep Underground Neutrino Experiment (DUNE) and THEIA.
