The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ(13) with a significance of 5.2 standard deviations. Antineutrinos from six 2.9 GWth reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470 m and 576 m) and one far (1648 m) underground experimental halls. With a 43,000 ton-GWth-day live-time exposure in 55 days, 10,416 (80,376) electron-antineutrino candidates were detected at the far hall (near… Expand

The Improved Measurement of Electron-antineutrino Disappearance at Daya Bay
With 2.5x the previously reported exposure, the Daya Bay experiment has improved the measurement of the neutrino mixing parameter sin^2(2theta_13) = 0.089+-0.010(stat)+-0.005(syst). ReactorExpand
Measurement of the Reactor Antineutrino Flux and Spectrum at Daya Bay.
A measurement of the flux and energy spectrum of electron antineutrinos from six 2.9 GWth nuclear reactors with six detectors deployed in two near and far underground experimental halls in the Daya Bay experiment finds the measured IBD positron energy spectrum deviates from both spectral predictions by more than 2σ over the full energy range.

Search for a light sterile neutrino at Daya Bay.
A search for light sterile neutrino mixing was performed with the first 217 days of data from the Daya Bay Reactor Antineutrino Experiment, and the relative spectral distortion due to the disappearance of electron antineUTrinos was found to be consistent with that of the three-flavor oscillation model.
