description | The Daya Bay experiment is designed to precisely measure the reactor antineutrino oscillation at a baseline around 2 km. Eight functionally identical detectors are placed at three underground experiment halls with distances between 360 m and 1900 m from six reactors. The Daya Bay experiment observed the reactor antineutrino disappearance at short baseline with a significance of 5.2σ in 2012. The Daya Bay experiment is continuously improving the precision of the mixing angle sin$^{2}$ 2θ$_{13}$ and effective neutrino mass-squared difference |Δm$_{ee}^{2}$| with growing statistics and better systematic uncertainties. In this talk, the latest results of sin$^{2}$ 2θ$_{13}$ and |Δm$_{ee}^{2}$| is reported with the 1958-day data sample of neutron-gadolinium capture events. As an independent measurement, the oscillation analysis is also performed using the neutron-hydrogen capture events. Besides the oscillation measurement, the progress on the measurement of reactor antineutrino flux and spectrum is also reported. |
