  14. From the press release: • The copious data revealed for the first time the strong signal of the effect that the scientists were searching for, a so‑called “mixing angle” named theta one-three (written θ13), which the researchers measured with unmatched precision. The Daya Bay collaboration’s first results indicate that theta one-three, expressed as sin2 2 θ13, is equal to 0.092 plus or minus 0.017. • “This is a new type of neutrino oscillation, and it is surprisingly large,” says Yifang Wang ……….

  15. “The Daya Bay experiment plans to stop the current data-taking this summer to install a second detector in the Ling Ao Near Hall, and a fourth detector in the Far Hall, completing the experimental design,” says Yifang Wang.
