Nuclear Recoil Identification in a Scientific Charge-Coupled Device
K. J. McGuire, A. E. Chavarria, N. Castello-Mor +19
Charge-coupled devices (CCDs) are a leading technology in direct dark matter searches because of their eV-scale energy threshold and high spatial resolution. The sensitivity of fut…
Search for Daily Modulation of MeV Dark Matter Signals with DAMIC-M
I. Arnquist, N. Avalos, D. Baxter +37
Dark Matter (DM) particles with sufficiently large cross sections may scatter as they travel through Earth's bulk. The corresponding changes in the DM flux give rise to a character…
Confirmation of the spectral excess in DAMIC at SNOLAB with skipper CCDs
A. Aguilar-Arevalo, I. Arnquist, N. Avalos +69
We present results from a 3.25 kg-day target exposure of two silicon charge-coupled devices (CCDs), each with 24 megapixels and skipper readout, deployed in the DAMIC setup at SNOL…
First Constraints from DAMIC-M on Sub-GeV Dark-Matter Particles Interacting with Electrons
I. Arnquist, N. Avalos, D. Baxter +42
We report constraints on sub-GeV dark matter particles interacting with electrons from the first underground operation of DAMIC-M detectors. The search is performed with an integra…
Precision measurement of Compton scattering in silicon with a skipper CCD for dark matter detection
D. Norcini, N. Castello-Mor, D. Baxter +41
Experiments aiming to directly detect dark matter through particle recoils can achieve energy thresholds of . In this regime, ionization signals from s…
EXCESS workshop: Descriptions of rising low-energy spectra
P. Adari, A. Aguilar-Arevalo, D. Amidei +303
Many low-threshold experiments observe sharply rising event rates of yet unknown origins below a few hundred eV, and larger than expected from known backgrounds. Due to the signifi…
Characterization of the background spectrum in DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, I. Arnquist +31
We construct the first comprehensive radioactive background model for a dark matter search with charge-coupled devices (CCDs). We leverage the well-characterized depth and energy r…
Constraints on Light Dark Matter Particles Interacting with Electrons from DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, D. Baxter +31
We report direct-detection constraints on light dark matter particles interacting with electrons. The results are based on a method that exploits the extremely low levels of leakag…
