Abstract

The successful measurements of the smallest neutrino mixing angle, θ₁₃, in 2012 by the short (1∼2 km) baseline reactor neutrinos experiments, Daya Bay, RENO, and Double Chooz, have triggered a golden age of neutrino physics. The three experiments have been improving the θ₁₃ measurements by accumulating event statistics and reducing systematic uncertainties. Now the θ₁₃ measurement is the most precise one among the mixing angles in the Pontecorvo-Maki-Nakagawa-Sakata matrix. The most updated θ₁₃ and Δm²_ee measurements from these experiments are reported here as well as the 5 MeV excess, absolute reactor neutrino flux and sterile neutrino search. The best final precision on the sin²2θ₁₃ (|Δm²_ee|) measurement is expected to be ∼3% (∼3%). A combined analysis from the three experiments will reduce the uncertainty and the relevant activity has started recently.
