Description
The existence of rapidly spinning black hole and ultralight boson capable of forming superradiant cloud around it can provide a non-zero lower bound on fermion couplings with the ultralight bosons. We propose that a hitherto unexplored manifestation of it in terms of neutrinos provide a minimal and concrete realization of the mechanism and can produce a diffuse cosmic background of neutrinos. In this work we try to connect the black hole superradiance and fundamental interactions with this new background and put lower bounds on such scalar and vector interactions.
