The KDK (potassium decay) experiment
P. C. F. Di Stefano, N. Brewer, A. FijaÅkowska +20
Potassium-40 (K) is a background in many rare-event searches and may well play a role in interpreting results from the DAMA dark-matter search. The electron-capture decay…
Deep-underground dark matter search with a COSINUS detector prototype
The COSINUS Collaboration, G. Angloher, M. R. Bharadwaj +36
Sodium iodide (NaI) based cryogenic scintillating calorimeters using quantum sensors for signal read out have shown promising first results towards a model-independent test of the…
Rare K decay with implications for fundamental physics and geochronology
M. Stukel, L. Hariasz, P. C. F. Di Stefano +24
Potassium-40 is a widespread, naturally occurring isotope whose radioactivity impacts subatomic rare-event searches, nuclear structure theory, and estimated geological ages. A pred…
Precision measurement of Zn electron-capture decays with the KDK coincidence setup
L. Hariasz, P. C. F. Di Stefano, M. Stukel +10
Zn is a common calibration source, moreover used as a radioactive tracer in medical and biological studies. In many cases, -spectroscopy is a preferred method of …
Quenching factors for Na recoils as a function of Tl dopant concentrations in NaI(Tl) crystals
G. Angloher, M. R. Bharadwaj, A. Böhmer +51
Thallium-doped sodium iodide (NaI(Tl)) scintillation detectors play an important role in the field of direct dark matter (DM) searches. The DAMA/LIBRA experiment stands out for its…
COSINUS model-independent sensitivity to the DAMA/LIBRA dark matter signal
G. Angloher, M. R. Bharadwaj, A. Böhmer +40
COSINUS is a dark matter direct detection experiment using NaI crystals as cryogenic scintillating calorimeters. If no signal is observed, this will constrain the dark matter scatt…
