摘要
The Daya Bay experiment was designed to measure the least known mixing angle in the three-flavor neutrino mixing framework, theta(13), with unprecedented precision by employing a relative rate measurement of electron antineutrinos from nuclear reactors. Data collected in a 217 day long period when six detectors were operational have been analyzed. Rate and energy spectra analysis yielded sin(2) 2 theta(13) = 0.090(-0.009)(+0.008), as well as a new result for an effective mass squared splitting Delta m(ee)(2) = 2.59(-0.20)(+0.19) x 10(-3)eV(2). The experiment started taking data in its full configuration with 8 detectors operational in fall 2012. We will briefly describe the experiment and the recent results. We will also overview future prospects of the experiment.
