New Results from RENO

الأصل · EN

RENO (Reactor Experiment for Neutrino Oscillation) is an experiment dedicated to measure the smallest neutrino mixing angle θ₁3 using reactor neutrinos in Korea. Our first result measured in 2012 using about 220 live days of data showed non-zero θ₁3 value with 4.9 σ significance. In March 2013 we updated our first result with improvements in both statistical and systematic errors using 403 live days of data. The measured value using rate-only analysis is sin²(2θ₁3) = 0.100 +/- 0.010 (stat) +/- 0.015 (sys.) corresponding to 6.3 σ significance. RENO has been taking data almost continuously since August 2011 and we have reached more than 800 live days of data that is currently being analyzed.
