Global analyses of neutrino
oscillation data
The Bari global analysis of neutrino oscillation data, published openly: best fits, allowed ranges, both mass orderings, and a parameter register you can download as JSON or CSV.
The six parameters, as measured
Best fit with 1σ and 3σ ranges, normal ordering, from Table I of Phys. Rev. D 111, 093006 (2025). Full tables and both orderings are on the results page.

normal ordering · arXiv:2503.07752, (1,2) sector updated in arXiv:2511.21650
Full tables and ranges →Normal ordering is favoured at 2.2σ; the χ² offset between the orderings is Δχ²(IO−NO) = +5.0. Four of the six values above — sin²θ₁₃, sin²θ₂₃, |Δm²| and δ/π, together with that ordering preference — are from Table I of Phys. Rev. D 111, 093006 (2025), the most recent full release, in the conventions stated there.
The two marked 2026 — δm² and sin²θ₁₂ — are newer. They come from Table I of Phys. Rev. D 114, 016026 (2026) (arXiv:2511.21650), which adds the first JUNO results and the latest SNO+ data to the 2025 analysis. It revises the (1,2) sector alone and does not touch the other four parameters, so this card set is the newest published value for each — not a single fit. Both papers define the percentage the same way, as their own “formal 1σ parameter accuracy”: a sixth of the 3σ range divided by the best fit, which is not the ordinary 1σ fractional uncertainty and does not equal half the 1σ range over the best fit. The parameter history carries every release, value by value.
Today on arXiv
Experimental and theoretical preprints of the day, kept in two streams and ranked by a keyword score whose word list is printed at the foot of that page — no model decides what appears there.
The full digest → NewsWhat is happening
Experiments, results and milestones, written from fetched sources: every item on that page carries the link it came from, and an item whose citation cannot be resolved is dropped before publication.
More news → ConferencesWhere the field meets
Upcoming and recent meetings with dates and links — and the venue wherever the source publishes one — rebuilt each day from the conference indexers rather than kept by hand.

formal 1σ accuracy · logarithmic scale
Each line is one parameter’s formal 1σ accuracy — a sixth of its 3σ range over its best fit — as published in each release. Computed from the same tables the parameter history is built on.
