Search for two-neutrino double electron capture in Ar with the DarkSide-50 detector
50 Collaboration, P. Agnes, I. F. M. Albuquerque +83
The DarkSide-50 experiment used low‑radioactivity liquid argon to search for the rare two‑neutrino double electron capture decay of ^36Ar, finding no signal and setting a half‑life…
First Nuclear Ultra-Heavy Dark Matter Search in Argon Time Projection Chambers with the DarkSide-50 Experiment
P. Agnes, I. F. Albuquerque, T. Alexander +125
We report the first search for nuclear ultra-heavy dark matter (UHDM) in a dual-phase liquid argon time projection chamber using the DarkSide-50 experiment. Unlike conventional wea…
Sensitivity to low-mass WIMPs with an improved liquid argon ionization response model within the DarkSide programme
F. Acerbi, P. Adhikari, P. Agnes +294
Dark matter detection experiments using liquid argon rely on a precise characterization of the ionization response to nuclear recoils, especially in the keV energy range relevant f…
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…
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…
Production, Quality Assurance and Quality Control of the SiPM Tiles for the DarkSide-20k Time Projection Chamber
F. Acerbi, P. Adhikari, P. Agnes +301
The DarkSide-20k dark matter direct detection experiment will employ a 21 m^2 silicon photomultiplier (SiPM) array, instrumenting a dual-phase 50 tonnes liquid argon Time Projectio…
