Wikipedia

  1. Muon

    A muon ( MYOO-on; from the Greek letter mu (μ) used to represent it) is an elementary particle similar to the electron, with an electric charge of −1 e and a spin of 1⁄2, but with a much greater mass. It is classified as a lepton. As with other leptons, the muon is not thought to be composed of any simpler particles; that is, it is a fundamental particle. The muon is an unstable subatomic particle with a mean lifetime of 2.2 μs, much longer than many other subatomic particles. As with the decay of the non-elementary neutron (with a lifetime around 15 minutes), muon decay is slow (by subatomic standards) because the decay is mediated only by the weak interaction (rather than the more powerful strong interaction or electromagnetic interaction), and because the mass difference between the muon and the set of its decay products is small, providing few kinetic degrees of freedom for decay. 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). Muons are denoted by μ− and antimuons by μ+. Formerly, muons were called mu mesons, but are not classified as mesons by modern particle physicists (see § History), and that name is no longer used by the physics community. Muons have a mass of 105.66 MeV/c2, which is approximately 206.7682830(46) times that of the electron, me. There is also a third lepton, the tau, approximately 17 times heavier than the muon. Due to their greater mass, muons accelerate more slowly than electrons in electromagnetic fields, and emit less bremsstrahlung (deceleration radiation). This allows muons of a given energy to penetrate far deeper into matter because the deceleration of electrons and muons is primarily due to energy loss by the bremsstrahlung mechanism. For example, so-called secondary muons, created by cosmic rays hitting the atmosphere, can penetrate the atmosphere and reach Earth's land surface and even into deep mines. Because muons have a greater mass and energy than the decay energy of radioactivity, they are not produced by radioactive decay. However they are produced in great amounts in high-energy interactions in normal matter, in certain particle accelerator experiments with hadrons, and in cosmic ray interactions with matter. These interactions usually produce pi mesons initially, which almost always decay to muons. As with the other charged leptons, the muon has an associated muon neutrino, denoted by νμ, which differs from the electron neutrino and participates in different nuclear reactions.

  1. muon

    A muon is a subatomic particle similar to an electron but is about 200 times heavier. It is a lepton and has a negative electric charge and a spin of 1/2. It is unstable and decays into other particles, including an electron and a neutrino. Muons and their antiparticles (muon neutrinos) participate in weak interactions, while muons also participate in electromagnetic interactions. They are a key component used in studies of particle physics.

  1. Muon

    The muon is an elementary particle similar to the electron, with unitary negative electric charge and a spin of ¹⁄2. Together with the electron, the tau, and the three neutrinos, it is classified as a lepton. As is the case with other leptons, the muon is not believed to have any sub-structure at all. The muon is an unstable subatomic particle with a mean lifetime of 2.2 µs. This comparatively long decay lifetime is due to being mediated by the weak interaction. The only longer lifetime for an unstable subatomic particle is that for the free neutron, a baryon particle composed of quarks, which also decays via the weak force. Muon decay produces at least three particles, and these must include an electron of the same charge as the muon, plus two neutrinos of different types. Like all elementary particles, the muon has a corresponding antiparticle of opposite charge but equal mass and spin: the antimuon. Muons are denoted by μ− and antimuons by μ+. Muons were previously called mu mesons, but are not classified as mesons by modern particle physicists.²

Examples of MUON in a Sentence

  1. Gabriella Sciolla:

    Z-prime is much heavier than a Z particle, something like tens of times the mass, z-prime can decay in a very simple way that yields two very energetic muons, which are basically heavier versions of electrons. If we can detect the muon signature of Z-prime, that would support models that predict the existence of Z-prime.
