Description

Primordial black holes (PBHs) with initial mass ~10^15 g are currently breathing their last breaths due to Hawking radiation. As transient burst events, their deaths are expected to produce copious amounts of neutrinos, both directly and indirectly from the decay of other emitted particle species. If such a PBH burst occurs in the local neighborhood, they can produce a detectable signal in our current neutrino telescopes, which have a larger field of view than gamma-ray telescopes traditionally used for PBH searches. We re-evaluate the expected neutrino flux from PBHs and discuss the potential of neutrino telescope in the search for PBHs. Also, in a multimessenger approach, we discuss the correlation between the neutrino and gamma-ray fluxes expected from evaporating PBHs. We argue that the larger field of view of neutrino telescopes and the peculiar multimessenger correlations are beneficial for the identification of PBHs, in case of detection.
