Characterization of spurious-electron signals in the double-phase argon TPC of the DarkSide-50 experiment
50 Collaboration, P. Agnes, I. F. Albuquerque +144
Spurious-electron signals in dual-phase noble-liquid time projection chambers have been observed in both xenon and argon Time Projection Chambers (TPCs). This paper presents the fi…
A study of events with photoelectric emission in the DarkSide-50 liquid argon Time Projection Chamber
50 Collaboration, P. Agnes, I. F. M. Albuquerque +135
Finding unequivocal evidence of dark matter interactions in a particle detector is a major objective of physics research. Liquid argon time projection chambers offer a path to prob…
Search for low-mass dark matter WIMPs with 12 ton-day exposure of DarkSide-50
50 Collaboration, P. Agnes, I. F. M. Albuquerque +139
We report on the search for dark matter WIMPs in the mass range below 10 GeV/c, from the analysis of the entire dataset acquired with a low-radioactivity argon target by the Da…
Fermionic sub-GeV Dark Matter from evaporating Primordial Black Holes at DarkSide-50
50 Collaboration, P. Agnes, I. F. Albuquerque +125
We present a search for boosted dark matter from Primordial Black Holes (PBH) evaporation using the DarkSide-50 ionization-signal-only dataset corresponding to the experiment's ($1…
Search for dark matter annual modulation with DarkSide-50
50 Collaboration, P. Agnes, I. F. M. Albuquerque +142
Dark matter induced event rate in an Earth-based detector is predicted to show an annual modulation as a result of the Earth's orbital motion around the Sun. We searched for this m…
Long-term temporal stability of the DarkSide-50 dark matter detector
50 Collaboration, P. Agnes, I. F. M. Albuquerque +142
The stability of a dark matter detector on the timescale of a few years is a key requirement due to the large exposure needed to achieve a competitive sensitivity. It is especially…
