XENONnT Detects Solar Neutrinos at Record-Low Energies
The XENONnT experiment at Italy’s Gran Sasso National Laboratory has successfully measured solar neutrinos via elastic neutrino-electron scattering at energies as low as 17 keV. This achievement, reported in a preprint, demonstrates the detector’s capability to probe low-energy particle interactions with a five-sigma confidence level, though it does not constitute a dark matter discovery.
