Abstract
The successful measurements of the smallest neutrino mixing angle, $\theta_{13}$, in 2012
by the short (1$\sim$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 $\theta_{13}$ measurements by accumulating event statistics
and reducing systematic uncertainties.
Now the $\theta_{13}$ measurement is the most precise one among the mixing angles in the Pontecorvo-Maki-Nakagawa-Sakata matrix.
The most updated $\theta_{13}$ and $\Delta m^{2}_{ee}$ 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 sin$^{2}2\theta_{13}$ ($|\Delta m^2_{ee}|$) measurement is expected to be $\sim$3\% ($\sim$3\%).
A combined analysis from the three experiments will reduce the uncertainty and the relevant activity has started recently.
