Nonzero neutrino mass is established through oscillation measurements of mass-squared differences; the absolute mass scale and Dirac-versus-Majorana nature remain unresolved.

This is an authored directed relation from the source endpoint to the target endpoint.
Neutrinos have nonzero but very small masses; the absolute scale and ordering are incompletely determined.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
wp-physics-neutrinonlab-physics-neutrinopdg-2026-neutrinopdg-rppwp-physics-neutrino_massnobel-neutrinoThis is an authored directed relation from the source endpoint to the target endpoint.
Observed flavor oscillations require at least two distinct neutrino mass eigenvalues.
Record a genuine theorem implication that is not part of the target definition; these edges may point toward a weaker structure.
