---++ About the experiment

The Daya Bay Neutrino Experiment is a neutrino-oscillation experiment designed to measure the mixing angle &theta;<sub>13</sub> using anti-neutrinos produced by the reactors of the Daya Bay Nuclear Power Plant (NPP) and the Ling Ao NPP. ยป [[/docs/experiment.html][More ... ]]
