Neutrinos from Primordial Black Hole Evaporation

Understand

Primordial Black Holes (PBHs) are candidates for dark matter as well as ultra-high energy cosmic rays.

• PBHs are speculated to exist over a large range of masses, from below $10^{15}$ g to $10^3$ M$_\odot$.
• Here we search for PBHs with an initial mass of $\sim 10^{15}$ g.
• Hawking radiation by black holes of this initial mass predicts their evaporation at present time.
