What was discovered
Detectors next to the reactors of a nuclear power plant measured the disappearance of antineutrinos and showed that the last mixing angle, θ13, is not zero. It opened the way to searching for CP violation in neutrinos.
RENO (South Korea) obtained a similar result weeks later; Double Chooz and T2K had given earlier hints.
What it led to
- mass hierarchy experiments (JUNO, DUNE)
- search for leptonic CP violation
