Description
The Daya Bay experiment has measured $sin^2(2\theta_{13})$ and $\Delta m^2_{32}$ with better than 4% precision using an inverse beta decay (IBD) sample tagged via neutron capture on gadolinium (nGd). A precise and independent measurement of the oscillation parameters is performed with IBDs tagged via neutron capture on hydrogen (nH), a statistically distinct sample with largely different systematic uncertainties. Efforts have gone into developing an energy model that improves the characterization of detector response. This enables a spectral measurement of reactor antineutrino disappearance with the nH sample. Data-driven methods have been developed to precisely estimate the backgrounds and to better control the systematic uncertainties. This work will be presented, along with the lastest nH oscillation results.
