An electrically neutral lepton occurring in three flavors; observed flavor oscillations imply nonzero neutrino masses beyond the minimal massless-neutrino Standard Model.

This is an authored directed relation from the source endpoint to the target endpoint.
Pauli proposed the neutrino to preserve conservation laws in continuous beta decay.
The source experiment, observation, anomaly, or problem materially motivated the development, revision, or acceptance of the target concept. Historical influence is not logical derivation; the edge detail states the documented role and avoids retrospective origin myths.
wp-physics-beta_decaynobel-neutrino-advancedThis is an authored directed relation from the source endpoint to the target endpoint.
Electron, muon, and tau neutrinos are neutral leptons.
The target is a member or subtype of the broader source class.

This is an authored directed relation from the source endpoint to the target endpoint.
Antineutrino denotes the charge-conjugate weak-interaction state or channel; whether it is a distinct particle from the neutrino depends on the unresolved Dirac-versus-Majorana question.
The target represents a state, property, observable, or state-dependent description associated with the source system or theory.
pdg-2026-neutrinowp-physics-antineutrinoThis is an authored directed relation from the source endpoint to the target endpoint.
Delayed coincidence signatures provided direct evidence for reactor antineutrinos.
The source theory, law, entity, prediction, or structural claim is directly tested, supported, constrained, or established by the target experiment or observation. Experimental support is not final logical proof; the edge detail states exactly what was measured.

This is a weak-interaction neutrino flavor state.
The target is a member or subtype of the broader source class.

Electron-, muon-, and tau-neutrino states are flavor-basis states of the neutrino sector.
The target is a member or subtype of the broader source class.
pdg-2026-neutrinonobel-neutrinoThis 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.
