Description
Primordial black holes are hypothetical Black Holes generated in the first instants of the Universe life. Focusing on Primordial Black Hole masses in the range [$5\times 10^{14}$ − $5\times 10^{15}$] g, we point out that the neutrinos emitted by PBHs evaporation can interact through the coherent elastic neutrino-nucleus scattering producing an observable signal in multi-ton Dark Matter direct detection experiments. The envisaged high exposures for the next-generation facilities allow us to limit Primordial Black Hole abundance today, improving the existing neutrino limits obtained with Super-Kamiokande. We also quantify how Primordial Black Holes would modify the “neutrino floor”.
