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 2 intriguing discrepancies with theoretical predictions and provide an important measurement that will shape future reactor neutrino experiments.

It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter’s dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.

The MicroBooNE detector – a so-called time projection chamber filled with 170 tons of liquid argon – spotted neutrinos that were generated when proton beams from Fermilab’s accelerator complex slammed into a target a few hundred yards away from the detector.

Researchers from Department of Energy’s SLAC National Accelerator Laboratory are developing tools for the acquisition of the experiment’s data and for the reconstruction of...
