Results on θ13 Neutrino Oscillations from Reactor Experiments

Definitive measurements of the smallest neutrino mixing angle theta(13) were made by Daya Bay, Double Chooz and RENO in 2012, based on the disappearance of electron antineutrinos emitted from reactors. The new generation reactor experiments have significantly improved a sensitivity for theta(13) down to the sin(2)(2 theta(13))similar to 0.01 level using two identical detectors of 10 similar to 40 tons at near (300 similar to 400 m) and far (1 similar to 2 km) locations. The theta(13) measurements by the three reactor experiments are presented with their future expected sensitivities.
