“…The inelastic ERDM scattering rate depends strongly on both the size of the target material's band gap and the detection threshold. Consequently, a semiconductor detector with sensitivity to single electron-hole (e − h þ ) pairs [14,15] can be competitive with other experimental technologies [16,17], even with a very modest exposure in an above-ground facility.…”

“…Constraints (shaded regions) and prospective sensitivities (solid colored lines) for axionlike particle (ALP) dark matter (left) and dark-photon (A ) dark matter (right), assuming that the ALP/A constitutes all the dark matter. Colored regions show constraints from XENON10, XENON100, and CDMSlite, as derived in this work, as well as the DAMIC results for A from [85]. Shaded bands around XENON10 and XENON100 limits show how the bound varies when changing the modeling of the secondary ionization in xenon.…”

We consider the absorption by bound electrons of dark matter in the form of dark photons and axion-like particles, as well as of dark photons from the Sun, in current and next-generation direct detection experiments. Experiments sensitive to electron recoils can detect such particles with masses between a few eV to more than 10 keV. For dark photon dark matter, we update a previous bound based on XENON10 data and derive new bounds based on data from XENON100 and CDMSlite. We find these experiments to disfavor previously allowed parameter space. Moreover, we derive sensitivity projections for SuperCDMS at SNOLAB for silicon and germanium targets, as well as for various possible experiments with scintillating targets (cesium iodide, sodium iodide, and gallium arsenide). The projected sensitivity can probe large new regions of parameter space. For axionlike particles, the same current direction detection data improves on previously known direct-detection constraints but does not bound new parameter space beyond known stellar cooling bounds. However, projected sensitivities of the upcoming SuperCDMS SNOLAB using germanium can go beyond these and even probe parameter space consistent with possible hints from the white dwarf luminosity function. We find similar results for dark photons from the sun. For all cases, direct-detection experiments can have unprecedented sensitivity to dark-sector particles.

“…We see that SENSEI closes a gap in laboratory probes of the large-ϵ region: the gap was bounded above by a measurement of the Rydberg constant (we show a 2σ constraint adapted from Refs. [57][58][59]) and below by our analysis of terrestrial absorption effects for XENON10, XENON100, CDMSlite, and DAMIC [4,[20][21][22]60] (stellar constraints [61,62] already disfavor this region).

SENSEI: First Direct-Detection Constraints on Sub-GeV Dark Matter from a Surface Run

et al. 2018

The Sub-Electron-Noise Skipper CCD Experimental Instrument (SENSEI) uses the recently developed Skipper-CCD technology to search for electron recoils from the interaction of sub-GeV dark matter particles with electrons in silicon. We report first results from a prototype SENSEI detector, which collected 0.019 g day of commissioning data above ground at Fermi National Accelerator Laboratory. These commissioning data are sufficient to set new direct-detection constraints for dark matter particles with masses between ∼500 keV and 4 MeV. Moreover, since these data were taken on the surface, they disfavor previously allowed strongly interacting dark matter particles with masses between ∼500 keV and a few hundred MeV. We discuss the implications of these data for several dark matter candidates, including one model proposed to explain the anomalously large 21-cm signal observed by the EDGES Collaboration. SENSEI is the first experiment dedicated to the search for electron recoils from dark matter, and these results demonstrate the power of the Skipper-CCD technology for dark matter searches.
