Abstract: Ultralight bosons can grow substantially in the vicinity of a black hole, through superradiant energy extraction. Consequently, such bosons can potentially reach field values close to the Planck scale, making black holes powerful transducers of such fields. If a scalar field couples to neutrino, it can trigger parametric production of neutrinos, and potentially quench their superradiant growth. During this saturation phase, scalar clouds can accelerate neutrinos to the TeV energy scale, generating fluxes that surpass those produced by atmospheric neutrinos.
