Chinese and American physicists are joining hands to conduct the world's largest neutrino experiment at the Daya Bay Nuclear Plant in south China.

The experiment, costing roughly 400 million yuan (50 million U.S. dollars), is designed to test the mixing angle of neutrino, 13, which is a vital measurement in the most advanced particle physics.

The Chinese Academy of Sciences and the Brookhaven National Laboratory and Lawrence Berkeley National Laboratory of the United States will participate in the significant underground experiment.
