### Description

Abstract: With eight identically designed underground detectors deployed at different baselines from six 2.9 GWth nuclear reactor cores, the Daya Bay Reactor Neutrino Experiment has achieved unprecedented precision in measuring the neutrino mixing angle $\theta_{13}$ and the neutrino mass-squared difference $\Delta m^2_{32}$ through the inverse beta decay (IBD) reaction with the final state neutron captured on gadolinium (nGd). The near-far relative measurement is the key to reduce the reactor and detector related systematic uncertainties. The experiment has stopped data taking with ~6 million antineutrino events collected from December 2011 to December 2022. The latest oscillation analysis results with the full dataset and improved systematic uncertainties will be presented in this poster.
