The DAMIC excess from WIMP-nucleus elastic scattering
A. E. Chavarria, H. Lin, K. J. McGuire +2
Two dark matter searches performed with charge-coupled devices (CCDs) in the DAMIC cryostat at SNOLAB reported with high statistical significance the presence of an unidentified so…
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…
Snowmass 2021 White Paper: The Selena Neutrino Experiment
A. E. Chavarria, C. Galbiati, B. Hernandez-Molinero +8
Imaging devices made from an ionization target layer of amorphous selenium (aSe) coupled to a silicon complementary metal-oxide-semiconductor (CMOS) active pixel array for charge r…
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…
Results on Low-Mass Weakly Interacting Massive Particles from a 11 kg d Target Exposure of DAMIC at SNOLAB (ICRC2021 Proceedings)
Michelangelo Traina
Experimental efforts of the last decades have been unsuccessful in detecting WIMPs (Weakly Interacting Massive Particles) in the 10-to-10 GeV/ range, thus motivating the s…
Measurement of the bulk radioactive contamination of detector-grade silicon with DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, D. Baxter +28
We present measurements of bulk radiocontaminants in the high-resistivity silicon CCDs from the DAMIC at SNOLAB experiment. We utilize the exquisite spatial resolution of CCDs to d…
Results on Low-Mass Weakly Interacting Massive Particles from an 11 kg-day Target Exposure of DAMIC at SNOLAB
A. Aguilar-Arevalo, D. Amidei, D. Baxter +29
We present constraints on the existence of weakly interacting massive particles (WIMPs) from an 11 kg-day target exposure of the DAMIC experiment at the SNOLAB underground laborato…
Cosmogenic activation of silicon
R. Saldanha, R. Thomas, R. H. M. Tsang +10
The production of H, Be, and Na by interactions of cosmic-ray particles with silicon can produce radioactive backgrounds in detectors used to search for rare eve…
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…
