One name. One construct. A landmark on the map.

How to read this

Every construct on the map is compared with every other by the meaning of its definitions, and the closest one is surfaced here. The nearest construct to neutrino is muon.

Hold this as a prompt, not a verdict. Two constructs sitting close in meaning is a reason to read them side by side and decide for yourself whether they are one idea under two names. It is not proof that they are. Compare the meanings in the Collider.

Particle physics

The nearly massless, weakly interacting neutral lepton

Wolfgang Pauli proposed the particle in a 1930 open letter to a physics conference at Tübingen, positing an unseen, electrically neutral, very light particle carried off in beta decay to account for the energy and spin that otherwise seemed to go missing and to violate conservation laws. Enrico Fermi built the first quantitative theory of beta decay around it in 1934 and gave it the name neutrino, Italian for 'little neutral one', and Clyde Cowan and Frederick Reines confirmed its existence experimentally in 1956 by detecting antineutrinos streaming from a nuclear reactor. A neutrino is a neutral lepton, a fundamental matter particle that carries no electric charge and has an extremely small mass, and that interacts only through the weak nuclear force and gravity. Because it barely interacts with matter, a neutrino passes through ordinary material almost undisturbed, which makes it a landmark case of a particle inferred from conservation bookkeeping decades before it could be observed, and today it is studied in three types, or flavors, that can transform into one another as they travel.[1][2][3]

Unit
A fundamental particle: a neutral lepton, one of the elementary matter particles of the Standard Model
Recovery means
Not applicable
Measured by
Detected indirectly through its rare weak-force interactions in large shielded detectors, for example inverse beta decay in reactor experiments or Cherenkov light in deep water and ice observatories
