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…
Study of the ionization efficiency for nuclear recoils in pure crystals
Youssef Sarkis, Alexis Aguilar-Arevalo, Juan Carlos D'Olivo
We study the basic integral equation in Lindhard's theory describing the energy given to atomic motion by nuclear recoils in a pure material when the atomic binding energy is taken…
Search for light mediators in the low-energy data of the CONNIE reactor neutrino experiment
Alexis Aguilar-Arevalo, Xavier Bertou, Carla Bonifazi +23
The CONNIE experiment is located at a distance of 30 m from the core of a commercial nuclear reactor, and has collected a 3.7 kg-day exposure using a CCD detector array sensitive t…
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…
