RENO experiment

The RENO experiment ( acronym for English Reactor experiment for neutrino oscillation ) is a neutrino experiment in South Korea to measure the last unknown neutrino mixing angle θ ₁₃ . The experiment is located in Yeonggwang in Jeollanam-do Province in the southwest of the Korean peninsula and is operated by a research group made up of scientists from various Korean universities. The mixing angle is determined indirectly by measuring a deficit of detected antineutrinos produced by the nearby Yeonggwang nuclear power plant .

On April 3, 2012, with corrections on April 8, the RENO group published a paper in which a non-zero mixing angle θ _{13 was} determined with a significance of 4.9 standard deviations :

${\displaystyle \sin ^{2}2\theta _{13}=0{,}113\pm 0{,}023}$

With this result, RENO confirmed the measurement of the Daya Bay experiment published a few weeks earlier as well as earlier, but not yet statistically significant results from T2K , MINOS and Double-Chooz .

Soo-Bong Kim is the chief scientist .
