The first set of experimental results from the Jiangmen Underground Neutrino Observatory used only 59.1 days of data but measured two neutrino oscillation parameters simultaneously with high precision. with researchers from many Thai institutions participating in global cooperation
Key findings
- 59.1 days of data were analyzed from the completion of the detector in August 2025.
- Sin²θ12 and Δm²21 are measured simultaneously and the accuracy is increased by approximately 1.6 times compared to the sum of the previous measurements.
- The results confirm the potential of the 20 kiloton detector for further studies of neutrino mass sequences.
Why this matters globally
JUNO is a large particle physics collaboration. The first results are published in Nature and are directly related to testing the neutrino model and searching for physics outside the Standard Model.

Limitations to consider
It is a result of the initial data. More data is still needed before the question of neutrino mass order can be definitively answered. And all raw data is not released to the public.
