The Daya Bay Reactor Neutrino Experiment

The 3x3 PMNS leptonic mixing matrix relates the mass and flavor eigenstates of the 3 known neutrinos. The $\theta_{13}$ mixing angle is the last unknown mixing angle in the PMNS matrix, the parameters of which must be determined experimentally. The Daya Bay experiment will search for the ``disappearance'' of reactor anti-neutrinos from the Daya Bay and Ling Ao Nuclear Power Plants located in Daya Bay, Guangdong, China using multiple identical detectors at different baselines. The disappearance probability of reactor anti-neutrinos at short baselines of 1-2km is directly proportional to $\sin^2 (2 \theta_{13})$. The goal of the Daya Bay experiment is to reach a sensitivity of $\sin^2 (2 \theta_{13})$ = 0.01 at the $90 \%$ C.L. The status and prospects of the experiment will be presented.
