Spectral Measurement of the Bi beta-decay to the Po Ground State with XENONnT
E. Aprile, J. Aalbers, K. Abe +170
We report the measurement of the Bi beta-decay spectrum to the ground state of Po using the XENONnT detector. This decay is classified as first-forbidden non-unique…
Radon Removal in XENONnT down to the Solar Neutrino Level
E. Aprile, J. Aalbers, K. Abe +169
The XENONnT experiment has achieved an exceptionally low Rn activity concentration within its inner 5.9tonne liquid xenon detector of (0.900.01stat.$\…
The neutron veto of the XENONnT experiment: Results with demineralized water
XENON Collaboration, E. Aprile, J. Aalbers +167
Radiogenic neutrons emitted by detector materials are one of the most challenging backgrounds for the direct search of dark matter in the form of weakly interacting massive particl…
Search for Light Dark Matter in Low-Energy Ionization Signals from XENONnT
E. Aprile, J. Aalbers, K. Abe +165
We report on a blinded search for dark matter with single- and few-electron signals in the first science run of XENONnT relying on a novel detector response framework that is physi…
XENONnT Analysis: Signal Reconstruction, Calibration and Event Selection
XENON Collaboration, E. Aprile, J. Aalbers +165
The XENONnT experiment, located at the INFN Laboratori Nazionali del Gran Sasso, Italy, features a 5.9 tonne liquid xenon time projection chamber surrounded by an instrumented neut…
