The Last Unknown Neutrino Mixing Angle Theta(13) And The Daya Bay Experiment

The neutrino mixing angle theta(13) is currently known to be small but had not been determined. The value of theta(13) is vital to resolving the neutrino mass heirarchy as well as future investigation of CP violation in the lepton sector. The Daya Bay Reactor Neutrino Experiment is designed to reach a sensitivity of 0.01 or better in sin(2) 2 theta(13) via an electron antineutrino disappearance signature.
