Constraints on Solar Reflected Dark Matter from a combined analysis of XENON1T and XENONnT data
XENON Collaboration, E. Aprile, J. Aalbers +174
We report on a search for sub-GeV dark matter upscattered via the solar reflection mechanism in the heavy mediator scenario. Under the Standard Halo Model, keV to MeV dark matter p…
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…
Challenging Spontaneous Quantum Collapse with XENONnT
E. Aprile, J. Aalbers, K. Abe +174
We report on the search for X-ray radiation as predicted from dynamical quantum collapse with low-energy electronic recoil data in the energy range of 1-140 keV from the first scie…
Characterization of the Hamamatsu R12699-406-M4 Photomultiplier Tube in Cold Xenon Environments
M. Adrover, L. Baudis, A. Bismark +5
The Hamamatsu R12699-406-M2 is a multi-anode 2-inch photomultiplier tube that offers a compact form factor, low intrinsic radioactivity, and high photocathode coverage.…
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.$\…
