Improved Measurement of Electron Antineutrino Disappearance at Daya Bay

Daya Bay Collaboration, F. P. An, Q. An +227

We report an improved measurement of the neutrino mixing angle ${\theta }_{13}$ from the Daya Bay Reactor Neutrino Experiment. We exclude a zero value for ${\sin }^{2}2{\theta }_{13}$ with a significan…
