First Direct-Detection Constraints on eV-Scale Hidden-Photon Dark Matter with DAMIC at SNOLAB


Abstract

We present direct detection constraints on the absorption of hidden-photon dark matter with particle masses in the range $1.2–30  eV c^{−2}$ with the DAMIC experiment at SNOLAB. Under the assumption that the local dark matter is entirely constituted of hidden photons, the sensitivity to the kinetic mixing parameter κ is competitive with constraints from solar emission, reaching a minimum value of $2.2 \times 10^{−14}$ at $17  eV c^{−2}$. These results are the most stringent direct detection constraints on hidden-photon dark matter in the galactic halo with masses $3–12  eV c^{−2}$ and the first demonstration of direct experimental sensitivity to ionization signals $< 12  eV$ from dark matter interactions.
