Abstract

This project aims to study signals from primordial black holes with masses $M \lesssim 10^{17}$g in neutrino experiments. In particular, we will focus on the sensitivity of the reactor neutrino oscillation experiment JUNO to the diffuse neutrino spectrum from primordial black holes in the few MeV energy range. A Beyond the Standard Model scenario where pseudo-Dirac neutrinos also contribute to the black hole evaporation will be investigated. The dependence of the results on the primordial black hole formation model will be evaluated.
