Abstract
he Jiangmen Underground Neutrino Observatory (JUNO) is a mul- tipurpose neutrino experiment currently under construction in South China. The detector consists of a 20 kton liquid scintillator target, contained inside a 35-meter- diameter spherical acrylic vessel submerged in an ultra-pure water pool. The central detector is equipped with 17612 20-inch photomultipliers and 25600 3-inch photo- multipliers, providing a total photocatode coverage of ≃ 78%. The experiment is primarily designed for the determination of neutrino mass ordering, through the measurement of the oscillation pattern of electron antineutrinos emitted from two nuclear power plants, at a baseline of about 52.5 km. In order to achieve high sta- tistical significance (∼ 3 − 4σ) in ∼ 6 years of data taking, an energy resolution ≤ 3% at 1 MeV is needed. JUNO will play a pivotal role in oscillation physics, measuring three oscillation parameters (sin2(θ12), Δm212, Δm232) with sub-percent precision. Moreover, the experiment will be able to detect neutrinos from sev- eral other sources, including solar neutrinos, atmospheric neutrinos, geoneutrinos, and core-collapse supernova neutrinos, opening up many research opportunities in physics and astrophysics. This contribution reviews the physics goals and current status of the JUNO project.
