Abstract:

Daya Bay is a new reactor neutrino experiment designed to determine the value of the unknown neutrino mixing angle $\theta_{13}$ with a sensitivity of better than 0.01 in $\sin^{2} 2\theta_{13}$. The measurement will be carried out by comparing the antineutrino flux and energy spectrum obtained with multiple detectors positioned at three different locations from three twin-core nuclear power plants at Daya Bay, China. The status of the experiment will be presented.
