Proposal for broad-range directional detection of light dark matter in cryogenic ice

Year: 2024

Type: article

Abstract: We propose hexagonal ice ( H 2 O ) as a new target for light dark matter (DM) direct detection. Ice, a polar material, is suitable for single phonon detection through DM scattering for which we consider light dark photon and light scalar mediator models. We report a rate sensitivity down to a DM mass of ∼ keV , constituting a broader mass range than other promising candidates. We find better sensitivity for near-term experimental thresholds from the presence of high-frequency phonons. These advantages, and ice’s availability, make it highly promising for single-phonon detection. Published by the American Physical Society 2024
