| The '''Daya Bay Reactor Neutrino Experiment''' is a [[China]]-based multinational [[particle physics]] project studying [[neutrino]]s. The multinational collaboration includes researchers from China, the United States, Taiwan, Russia, and the Czech Republic. The US side of the project is funded by the [[United States Department of Energy|US Department of Energy]]'s Office of High Energy Physics.
| |
| | |
| It is situated at [[Daya Bay]], approximately 52 kilometers northeast of [[Hong Kong]] and 45 kilometers east of [[Shenzhen]]. There is an affiliated project in the [[Aberdeen Tunnel Underground Laboratory]] in Hong Kong. It measures the [[neutron]]s produced by [[cosmic ray|cosmic]] [[muon]]s which may affect the Daya Bay Reactor Neutrino Experiment.

| ==Neutrino oscillations==
| |
| The experiment studies [[neutrino oscillations]] and is designed to measure the [[mixing angle]] [[PMNS matrix|''θ''<sub>13</sub>]] using [[antineutrino]]s produced by the reactors of the [[Daya Bay Nuclear Power Plant]] and the [[Ling Ao Nuclear Power Plant]]. Scientists are also interested in whether neutrinos are [[CP-violation|CP violators]].

| | |
| On 8 March 2012, the Daya Bay collaboration announced<ref>{{cite journal|author=Daya Bay Collaboration|arxiv=1203.1669|title=Observation of electron-antineutrino disappearance at Daya Bay|year=2012|journal=Physical Review Letters|volume=108|issue=17|pages=171803|doi=10.1103/PhysRevLett.108.171803|arxiv=1203.1669|bibcode = 2012PhRvL.108q1803A }}</ref><ref>{{cite web|author=Adrian Cho|url=http://news.sciencemag.org/sciencenow/2012/03/physicists-in-china-nail-a-key.html|title=Physicists in China Nail a Key Neutrino Measurement|date=8 March 2012|publisher=ScienceNow}}</ref><ref>{{cite web|author=Eugenie Samuel Reich

| : <math> \sin^2 (2\theta_{13}) = 0.092 \pm 0.016 \, \mathrm{(stat)} \pm 0.005\, \mathrm{(syst)}. </math>
| |
| | |
| This significant result represents a new type of oscillation and is surprisingly large.<ref>http://neutrino.physics.berkeley.edu/news/News.html</ref> It is consistent with earlier, but less significant results by [[T2K]], [[MINOS]] and [[Double Chooz]]. With ''θ''<sub>13</sub> so large, [[NOνA]] has about a 50% probability of being sensitive to the neutrino mass hierarchy. Experiments may also be able to probe CP violation among neutrinos.
