The Daya Bay reactor neutrino experiment observed electron antineutrino disappearance associated with with a significance better than in 2012. The final two of eight antineutrino detectors were installed in the summer of 2012. Including the 404 days of data collected with the full detector configuration resulted in a 3.6 times increase of statistics over the previous result with the 6-AD configuration. With improvements of the systematic uncertainties and better estimation of backgrounds, Daya Bay has measured and ~eV. This is the most precise measurement of to date and the most precise measurement of of via electron antineutrino disappearance. Several other analysis results are presented, including an independent measurement of using inverse-beta decays associated with neutron capture on hydrogen, a measurement of reactor antineutrino flux and spectrum, and a search for light sterile neutrino mixing.
