News & Events

The Jiangmen Underground Neutrino Observatory (JUNO) collaboration posted its first measurement of reactor neutrino oscillations in November. The higher precision sin2 θ12 and Δm221 neutrino oscillation parameter estimates are already generating discussion about normal vs. inverted mass hierarchy likelihoods based on the new measurements and existing data in this Jan. 14 arXiv post.

JUNO is designed to run for  up to 30 years, with an upgrade possible that would enable the search for neutrinoless double‑beta decay.

There’s a public outreach-friendly overview of JUNO’s early operations in CERN Courier.
