Constraints on elastic neutrino nucleus scattering in the fully coherent regime from the CONUS experiment

Understand

We report the best limit on coherent elastic scattering of electron antineutrinos emitted from a nuclear reactor off germanium nuclei.

• The measurement was performed with the CONUS detectors positioned at 17.1m from the 3.9GWth reactor core of the nuclear power plant in Brokdorf, Germany.
• The antineutrino energies of less than 10 MeV assure interactions in the fully coherent regime.
• The analyzed dataset includes 248.7 kgd with the reactor turned on and background data of 58.8 kgd with the reactor off.
