Most precise measurement of reactor antineutrino spectrum reveals intriguing surprise

(Chinese Academy of Sciences Headquarters) Members of the International Daya Bay Collaboration, who track the production and flavor-shifting behavior of electron antineutrinos generated at a nuclear power complex in China, have obtained the most precise measurement of these subatomic particles' energy spectrum ever recorded. The data generated from the world's largest sample of reactor antineutrinos indicate two intriguing discrepancies with theoretical predictions and provide an important measu...
