JUNO Sensitivity to Resonant Absorption of Galactic Supernova Neutrinos by Dark Matter

TL;DR

The paper explores JUNO's potential to detect resonant absorption features in supernova neutrino spectra caused by dark matter interactions, which could reveal or limit dark matter-neutrino couplings.

Contribution

It proposes using JUNO's energy resolution to identify spectral dips indicative of dark matter-neutrino interactions, providing a new method to probe such couplings.

Findings

JUNO can detect spectral dips caused by dark matter interactions.

The experiment can constrain or confirm specific dark matter-neutrino coupling models.

Resonant absorption features can serve as signatures of dark matter presence.

Abstract

Resonant interactions between neutrinos from a Galactic supernova and dark matter particles can lead to a sharp dip in the neutrino energy spectrum. Due to its excellent energy resolution, measurement of this effect with the JUNO experiment can provide evidence for such couplings. We discuss how JUNO may confirm or further constrain a model where scalar dark matter couples to active neutrinos and another fermion.
