Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a multipurpose neutrino experiment located in Kaiping (south China), ∼53 km distant from Yangjiang and Taishan Nuclear Power Plants, with the main goal of determining the Neutrino Mass Ordering (NMO). The experiment is located 650 m underground and the main detector consists of a central transparent acrylic sphere, with a ∼ 35 m diameter, which is filled with 20 kton of liquid scintillator and surrounded by ∼ 43000 photomultiplier tubes (PMT). The central detector is immersed in a water pool which work as muons veto system.
JUNO has recently started its data taking on august 2025. So far it released the first simultaneous high-precision determination of two neutrino oscillation parameters ((sin θ12)^2 and (∆m 21)^2) improving the precision with respect to the state-of-the-art by a factor of 1.6.
In this poster I will present an overview of the JUNO detector and report the first science results on neutrino oscillation physics.
