Daya Bay Reactor Neutrino Experiment
Encyclopedia
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, and the Czech Republic. The US side of the project is funded by the US Department of Energy
's Office of High Energy Physics. The experiment studies neutrino oscillations and is designed to measure the mixing angle θ13 using antineutrinos 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 violators.
It is situated at Daya Bay
, approximately 52 kilometers north 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

Particle physics
Particle physics is a branch of physics that studies the existence and interactions of particles that are the constituents of what is usually referred to as matter or radiation. In current understanding, particles are excitations of quantum fields and interact following their dynamics...

Neutron
The neutron is a subatomic hadron particle which has the symbol or , no net electric charge and a mass slightly larger than that of a proton. With the exception of hydrogen, nuclei of atoms consist of protons and neutrons, which are therefore collectively referred to as nucleons. The number of...
