摘要： The Daya Bay neutrino experiment has recently updated the oscillation analysis results with 621 days of data in 2015, which has 3.6 times more statistics than the previous publication in 2014. The relative ν¯e rate and spectrum measurement between the near and far detectors yielded the best fit values of sin22θ13 = 0.084 ± 0.005 and |Δm2ee| = (2.42 ± 0.11) × 10−3 eV2. This is currently the most precise measurement of sin22θ13   in the world. The measurement of |Δm2ee| also has a precision that is comparable to the measurements from MINOS and T2K experiments in 2014. Daya Bay also performed several other analyses such as the search for the light sterile neutrino in the 3+1 neutrino framework, and the measurements of the absolute reactor anti-neutrino flux and spectrum.
