Description
Black hole superradiance provides a unique mechanism for probing particle production. In this work, we investigate the extragalactic neutrino flux produced by quenched superradiance around Primordial Black Holes (PBHs).
We calculate and compare the neutrino flux and peak energy across various coupling constants and light boson masses for both the scalar and vector cases. On our poster, we showcase examples of the extragalactic flux components for the scalar superradiance clouds. By superimposing these signals onto known neutrino backgrounds—including Solar, Reactor, and Geoneutrinos—our numerical results reveal a distinct, clean neutrino signal in the MeV-GeV energy range.
As a next step, we aim to construct exclusion plots to constrain the parameter space using extragalactic and galactic neutrino spectra.
