Primordial Black Holes (PBHs) are Black holes formed in the early universe. They evaporate emitting all the elementary particles whose mass is lower than the PBHs temperature. We focused on PBHs whose mass is the range [5 × 10 14 , 8 × 10 15 ]g. We studied their neutrinos emission. These neutrinos can interact via coherent elastic neutrino-nucleus scattering (CEvNS) producing a signal in multi-ton DM direct detection experiments. We show that is possible to set bounds on the PBHs abundance. This talk is based on Ref.[1].
