The muon neutrino is an elementary particle which has the symbol. ν. μ and zero electric charge. Together with the muon it forms the second generation of leptons, hence the name muon neutrino. It was discovered in 1962 by Leon Lederman, Melvin Schwartz and Jack Steinberger. The discovery was rewarded with the 1988 Nobel Prize in Physics .
Muon decay almost always produces at least three particles, which must include an electron of the same charge as the muon and two types of neutrinos. Like all elementary particles, the muon has a corresponding antiparticle of opposite charge (+1 e ) but equal mass and spin: the antimuon (also called a positive muon ).
The proton and neutron are thus not elementary particles because they consist of smaller, constituent quarks. The electron, however, is a fundamental pointlike particle. Neutrinos, like their charged lepton partners, are also fundamental, elementary particles. All three neutrinos are very light and are stable.
24. Mai 2018 · The particle, a heavy version of the electron that rains down on every square centimetre of Earth, is little known outside particle physics — and last year it helped archaeologists to make a...

19. Apr. 2024 · neutrino, elementary subatomic particle with no electric charge, very little mass, and 1/2 unit of spin. Neutrinos belong to the family of particles called leptons, which are not subject to the strong force. Rather, neutrinos are subject to the weak force that underlies certain processes of radioactive decay.

31. Juli 2015 · A simple explanation was that the neutrino and antineutrino were of two different types that could not combine. This experiment convinced physicists that a second type of neutrino—the muon neutrino—indeed existed, winning the 1988 Nobel Prize in Physics for Schwartz, Lederman, and Steinberger.
The experiment of the Nobel Prize winners not only showed that the muon and the muon neutrino form a pair, it also showed that the other two leptons, the electron and the electron neutrino, form a pair. The grouping in pairs of elementary particles is fundamental in particle physics and became even more significant after the establishment of ...
