Description
In the three-flavor neutrino mixing framework, $\theta_{13}$ was the least known mixing angle. The Daya Bay experiment was designed to measure this parameter with unprecedented precison through a relative measurement with eight functionally identical electron anti-neutrino detectors deployed at three experimental halls near three high-power nuclear reactor complexes in south China. In March 2012 the Daya Bay experiment discovered the non-zero value of $\sin^{2}2\theta_{13}=0.092 \pm 0.016 \pm 0.005$ with significance better than $5\sigma$. The Daya Bay experiment is continuously improving the precision of $\sin^{2}2\theta_{13}$ and the effective neutrino mass squared difference $|\Delta m^{2}_{ee}|$ with more statistics, less background and better control of systematics. In this talk, I will report the latest status on the measurement of $\sin^{2}2\theta_{13}$ and $|\Delta m^{2}_{ee}|$ from the Daya Bay experiment.
