Title: Measurement of the Electron Antineutrino Oscillation with 1958 Days of Operation at Daya Bay

Abstract

Here, we report a measurement of electron antineutrino oscillation from the Daya Bay Reactor Neutrino Experiment with nearly 4 million reactor ¯ν e inverse β decay candidates observed over 1958 days of data collection. The installation of a flash analog-to-digital converter readout system and a special calibration campaign using different source enclosures reduce uncertainties in the absolute energy calibration to less than 0.5% for visible energies larger than 2 MeV. The uncertainty in the cosmogenic 9Li and 8He background is reduced from 45% to 30% in the near detectors. A detailed investigation of the spent nuclear fuel history improves its uncertainty from 100% to 30%. Analysis of the relative ¯ν e rates and energy spectra among detectors yields sin 213 = 0.0856 ± 0.0029 and Δm 2 32 = (2.471 +0.068 –0.070) × 10 –3 eV 2 assuming the normal hierarchy, and Δm 2 32 = –(2.575 +0.068 –0.070) × 10 –3 eV 2 assuming the inverted hierarchy.
