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)…
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…
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…
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.
Low-Mass Dark Matter Search with the DarkSide-50 Experiment
The DarkSide Collaboration, P. Agnes, I. F. M. Albuquerque +192
We present the results of a search for dark matter WIMPs in the mass range below 20 GeV/c^2 using a target of low-radioactivity argon. The data were obtained using the DarkSide-50…
Electroluminescence pulse shape and electron diffusion in liquid argon measured in a dual-phase TPC
P. Agnes, I. F. M. Albuquerque, T. Alexander +163
We report the measurement of the longitudinal diffusion constant in liquid argon with the DarkSide-50 dual-phase time projection chamber. The measurement is performed at drift elec…
