New results from RENO and prospects with RENO-50

Understand

RENO (Reactor Experiment for Neutrino Oscillation) has made a definitive measurement of the smallest mixing angle theta13 in 2012, based on the disappearance of electron antineutrinos.

• More precise measurements have been obtained and presented on the mixing angle and the reactor neutrino spectrum, using ~800 days of data.
• We have observed an excess of IBD prompt spectrum near 5 MeV with respect to the most commonly used models.
• The excess is found to be consistent with coming from reactors.
