Recent results from reactor antineutrino experiments

Abstract

The smallest neutrino mixing angle $\theta_{13}$ has been successfully measured by the disappearance of reactor antineutrinos at RENO, Daya Bay, and Double Chooz. The oscillation frequency is also measured based on energy and baseline dependent disappearance probability of reactor antineutrinos. Recent results fi nd a variation in the observed reactor antineutrino flux as a function of the reactor fuel evolution. We report more precisely measured values of $\theta_{13}$ and $\Delta m^2_{ee}$ and results on the evolution of observed reactor antineutrino yield and spectrum.
