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.
Neutrinos sind elektrisch neutrale Elementarteilchen mit sehr geringer Masse. Im Standardmodell der Elementarteilchenphysik existieren drei Arten ( Generationen) von Neutrinos: Elektron-, Myon- und Tau-Neutrinos. Jede Neutrino-Generation besteht aus dem Neutrino selbst und seinem Anti-Neutrino.
Das Myon (Englisch: Muon) ist ein Elementarteilchen, das in vielen Eigenschaften dem Elektron ähnelt. Wie das Elektron besitzt es eine negative Elementarladung und einen Spin von 1⁄2. Myon und Elektron unterliegen der elektroschwachen, jedoch nicht der starken Wechselwirkung und gehören damit zu den Leptonen.
There are three known types (flavors) of neutrinos: electron neutrino ν e, muon neutrino ν μ, and tau neutrino ν τ, named after their partner leptons in the Standard Model (see table at right). The current best measurement of the number of neutrino types comes from observing the decay of the Z boson.

The dominant muon decay mode (sometimes called the Michel decay after Louis Michel) is the simplest possible: the muon decays to an electron, an electron antineutrino, and a muon neutrino. Antimuons, in mirror fashion, most often decay to the corresponding antiparticles: a positron, an electron neutrino, and a muon antineutrino. In ...
In particle physics, a lepton is an elementary particle of half-integer spin ( spin) that does not undergo strong interactions. [1] Two main classes of leptons exist: charged leptons (also known as the electron -like leptons or muons), including the electron, muon, and tauon, and neutral leptons, better known as neutrinos.
The Antarctic Muon And Neutrino Detector Array (AMANDA) is a neutrino telescope located beneath the Amundsen–Scott South Pole Station. In 2005, after nine years of operation, AMANDA officially became part of its successor project, the IceCube Neutrino Observatory.
