Neutrino and Positron Constraints on Spinning Primordial Black Hole Dark Matter

Ray, Anupam; Laha, Ranjan; Dasgupta, Basudeb

Primordial black holes can have substantial spin—a fundamental property that has a strong effect on its evaporation rate. We conduct a comprehensive study of the detectability of primordial black holes with non-negligible spin, via the searches for the neutrinos and positrons in the MeV energy range. Diffuse supernova neutrino background searches …
