摘要:An independent measurement of neutrino oscillation angle θ13using samples based on neutron captured on hydrogen (nH) was performed at the Daya Bay Reactor Neutrino Experiment. To deal with the challenges due to larger backgrounds, longer neutron capture time and lower detection efficiency, the nH analysis developed several data-driven techniques to precisely measure backgrounds and to control systematic uncertainties. This statistically independent and largely systematically uncorrelated independent analysis provides a firm confirmation of the nGd result and improves the overall uncertainty of sin2(2θ13). With 621 days of data and two newly installed antineutrino detectors, nH analysis yields sin2(2θ13) = 0.071 ± 0.011 in the three neutrino oscillation framework.
