The Nature of Massive Neutrinos

Table 1

The best-fit values and 3𝜎 allowed ranges of the 3-neutrino oscillation parameters, derived in [33] from a global fit of the current neutrino oscillation data. The values (values in brackets) correspond to 𝑚₁<𝑚₂<𝑚₃ (𝑚₃<𝑚₁<𝑚₂). The definition of Δ𝑚²_𝐴 used is: Δ𝑚²_𝐴=𝑚²₃−(𝑚²₂+𝑚²₁)/2.
