摘要: In this poster, we present the latest measurement of electron antineutrino disappearance using the fully constructed Daya Bay Reactor Neutrino Experiment. A total exposure of 6.9×105 GWth ton days was achieved in November 2013 after 617 day of data taking. The most precise estimates to date of the neutrino mass and mixing parameters |Δm2ee| and sin22θ13 were obtained with an analysis of the relative antineutrino rates and energy spectra between detectors. The value of the two parameters was found to be sin22θ13=0.084±0.005 and |Δm2ee|=(2.42±0.11)×10−3eV2. This report focuses in particular on describing how improvements in the calibration and in the energy response model contributed to achieve this result.

摘要: JUNO is a 20 kt Liquid Scintillator Antineutrino Detector currently under construction in the south of China. This report reviews JUNO's physics programme related to all neutrino sources but reactor antineutrinos, namely neutrinos from supernova burst, solar neutrinos and geoneutrinos.
