Description
on behalf of Daya Bay Collaboration
The Daya Bay experiment was planned to precisely measure the neutrino oscillation parameters $\sin^2 2\theta_{13}$ and $\Delta m^2_{32}$. The antineutrino flux from six nuclear reactors was measured by eight identically designed liquid scintillator detectors at distances from 400 m to 2 km. Four detectors were located in the two near halls and four detectors were located in the far hall. The experiment has accumulated $5.55 \times 10^6$ candidates of the interaction of electron antineutrinos during 10 years of operation. The oscillation parameters are measured with unprecedented precision: $\sin^2 2\theta_{13} = 0.0851 \pm 0.0024$, $\Delta m^2_{32} = (2.466 ± 0.060) \times 10^{−3}$ eV$^2$ assuming the normal mass ordering and $\Delta m^2_{32} = −(2.571 \pm 0.060) × 10^{−3}$ eV$^2$ assuming the inverted mass ordering.
Results of oscillation analysis based on a full dataset will be presented. Additionally, results of the search of sterile neutrinos are included as well.
