Description
Neutrino physics is one of the most active frontiers. Many puzzles remain in neutrinos, which may lead to new physics beyond the Standard Model of particle physics. Neutrino oscillation established in past two decades implies that neutrinos have tiny mass, a new phenomenon beyond the Standard Model. Daya Bay discovered a new type of neutrino oscillation in 2012 and measured the corresponding neutrino mixing angle θ13, by detecting reactor neutrinos. So far we have been measured 5 out of the 6 parameters that describe the neutrino oscillation, which the Charge-Parity phase δCP and the sign of the mass splitting Δm232 (so-called mass hierarchy) are unknown. The being-built Jiangmen Underground Neutrino Observatory (JUNO) aims at determination of the neutrino mass hierarchy and precise measurement of three neutrino mixing parameters by detecting reactor neutrinos at a distance of 53 km. JUNO was proposed in 2008 and formally approved in 2013. With a very challenging 20 kton liquid scintillator detector of 3% energy resolution, JUNO will also be promising in studying supernovae neutrino, solar neutrino, geo-neutrino, atmospheric neutrino, as well as other exotic searches. Progresses on the JUNO physics, detector design and R&D will be reported.
