New Results from RENO
Abstract
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.
