Entering the era of subpercent precision

Global three-flavour analysis including the latest solar, atmospheric, reactor and long-baseline accelerator data, combined with cosmological constraints.

Best-fit values and 3σ ranges from the 2025 global analysis (Table 1 of the paper), normal ordering. The fractional accuracy is the 1σ precision defined there as one sixth of the 3σ range. Δm² is defined as m₃² − (m₁² + m₂²)/2. See the paper for the inverted ordering. NO is favoured over IO at 2.2σ.

Bari group results — second release

Δχ² tables, one- and two-dimensional profiles and the figures of the Bari global analysis including the JUNO second release, served as an interactive notebook that runs entirely in the browser. The underlying .npz and text tables are downloadable from the same page.
