Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a multi-purpose neutrino experiment in southern China, built 650 m underground and positioned 52.5 km from the Yangjiang and Taishan nuclear power plants. Its primary goals are to determine the neutrino mass ordering and measure the oscillation parameters sin²θ₁₂, Δm²₂₁, and Δm²₃₁ with unprecedented precision.
To achieve these goals, the detector features a 20-kiloton ultra-pure liquid scintillator in a 17.7-m-radius acrylic sphere, instrumented with 17,596 large (20-inch) and 25,587 small (3-inch) photomultiplier tubes, surrounded by a water pool and an external plastic scintillator top tracker for background rejection. After over a decade of construction and commissioning, JUNO began physics data taking on August 26, 2025. With just 59 days of initial data, the experiment has already delivered world-leading measurements of sin²θ₁₂ and Δm²₂₁. This talk will present a comprehensive overview of JUNO and latest physics results.
