Abstract

The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ ₁₃ with a significance of 5.2 standard deviations. Antineutrinos from six 2.9GW _th reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470m and 576m) and one far (1648m) underground experimental halls. With a 43000ton-GW _th-day live-time exposure in 55 days, 10416 (80376) electron-antineutrino candidates were detected at the far hall (near halls). The ratio of the observed to expected number of antineutrinos at the far hall is R=0.940±0.011(stat.)±0.004(syst.). A rate-only analysis finds ^sin22θ ₁₃=0.092±0.016(stat.)±0. 005(syst.) in a three-neutrino framework.

N2 - The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ 13 with a significance of 5.2 standard deviations. Antineutrinos from six 2.9GW th reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470m and 576m) and one far (1648m) underground experimental halls. With a 43000ton-GW th-day live-time exposure in 55 days, 10416 (80376) electron-antineutrino candidates were detected at the far hall (near halls). The ratio of the observed to expected number of antineutrinos at the far hall is R=0.940±0.011(stat.)±0.004(syst.). A rate-only analysis finds sin22θ 13=0.092±0.016(stat.)±0. 005(syst.) in a three-neutrino framework.
