Abstract

The Daya Bay reactor neutrino experiment is the first experiment that measured a non-zero value for the neutrino mixing angle θ13\theta_{13} in 2012. Antineutrinos from six 2.9 GWth_{\text{th}} reactors are detected in eight identically designed detectors deployed in two near and one far underground experimental halls. The near-far arrangement in km-scale baselines of anti-neutrino detectors allows for a high-precision test of the three-neutrino oscillation framework. Daya Bay's collection of physics data already ended on December 12, 2020. This proceeding shows the measurement results of θ13\theta_{13} and the mass-squared splitting Δm322\Delta m^2_{32}, based on the gadolinium-capture tagged sample in the complete data set with 3158 days of operation. The latest results on the hydrogen-capture-based oscillation analysis and search for light sterile neutrino are also summarized.
