Constraints on Sub-GeV Dark Matter-Electron Scattering from the DarkSide-50 Experiment
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +193
We present new constraints on sub-GeV dark matter particles scattering off electrons in argon based on an analysis of ionization signal data from the DarkSide-50 detector.
Measurement of the ion fraction and mobility of Po produced in Rn decays in liquid argon
P. Agnes, I. F. M. Albuquerque, T. Alexander +163
We report measurements of the charged daughter fraction of Po as a result of the Rn alpha decay, and the mobility of Po ions, using radon-polonium coinc…
Effective field theory interactions for liquid argon target in DarkSide-50 experiment
50 Collaboration, P. Agnes, I. F. M. Albuquerque +164
We reanalize data collected with the DarkSide-50 experiment and recently used to set limits on the spin-independent interaction rate of weakly interacting massive particles (WIMPs)…
DarkSide-50 532-day Dark Matter Search with Low-Radioactivity Argon
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +172
The DarkSide-50 direct-detection dark matter experiment is a dual-phase argon time projection chamber operating at Laboratori Nazionali del Gran Sasso. This paper reports on the bl…
SiPM-matrix readout of two-phase argon detectors using electroluminescence in the visible and near infrared range
The DarkSide collaboration, C. E. Aalseth, S. Abdelhakim +312
Proportional electroluminescence (EL) in noble gases is used in two-phase detectors for dark matter searches to record (in the gas phase) the ionization signal induced by particle…
Design and construction of a new detector to measure ultra-low radioactive-isotope contamination of argon
The DarkSide Collaboration, C. E. Aalseth, S. Abdelhakim +328
Large liquid argon detectors offer one of the best avenues for the detection of galactic weakly interacting massive particles (WIMPs) via their scattering on atomic nuclei. The liq…
