| contents | The Daya Bay reactor neutrino experiment is the first experiment that measured a nonzero value for the $θ_{13}$ neutrino mixing angle in 2012. Antineutrinos from six 2.9 GW$_{\text{th}}$ reactors are detected in eight functionally identical antineutrino detectors deployed in two near (flux-weighted baseline 470 m and 576 m) and one far (1648 m) underground experimental halls. The near-far arrangement of antineutrino detectors allows for a relative measurement by comparing the observed antineutrino rates at various baselines. In 2014, the Daya Bay experiment reported an independent measurement of the nonzero neutrino oscillation parameter $θ_{13}$, utilizing the data set of neutron captured on hydrogen ($n$H) with distinct systematic uncertainties from the data set of neutrons captured on gadolinium, and has been improving this measurement since then. The latest result of the Daya Bay $n$H neutrino oscillation analysis with improved statistics and systematic control is presented. |
