Muon (represented by the Greek letter mu (μ)) is an elementary particle similar to an electron, with an electric charge of -1e i.e. electric charge and a spin of 1/2, but with greater mass. It is classified as Lipton. As with other leptons. Muon is not considered to have any sub-structure – that is, it is not believed to be composed of any simple particles.

Definition of ‘muon’

Muon is an unstable sub-atomic particle i.e. an unstable subatomic particle, whose average lifetime is 2.2 μs, which is longer than that of many other sub-atomic particles. With non-primary neutron decay (decay) (with a lifetime of around 15 minutes), Muon decay (decay) is slow (by subatomic parameters). Because decay is mediated by a particularly weak interaction (rather than a more powerful strong energy or electromagnet), and because the mass difference between Muon and its set of decay products is small, which decays. Provides some kinetic degree of freedom from. Moon decay almost always produces at least three particles, consisting of electrons of the same charge and two neutrinos of different types.

Muon’s charge

Like all elementary particles, the muon has a similar antiparticle of opposite charge (+ 1e), but with the same mass and spin as the antimuon (also called a positive muon).

Muon is denoted by μ− and antimuon μ +. The muon was previously called mu mesons, but modern muon particles are not classified as mu mesons by physicists, and the name is no longer used by the physics community.

Mass of muon

The mass of the muons is 105.66 MeV / c2, which is about 207 times that of the electron. Due to their greater mass, they do not accelerate rapidly when they encounter an electromagnetic field and do not emit much deceleration radiation. This allows muons of a given energy to penetrate much deeper than electrons, as the deceleration of electrons and muons is mainly due to the loss of energy by deceleration radiation. As an example, so-called “secondary muons”, originating from cosmic rays hitting the atmosphere, can penetrate to the Earth’s surface, and even into deep mines.

Since muons have a much larger mass and energy than decay energy of radioactivity, they are never generated by radioactive decay. However, in general, the matter is produced abundantly in high-energy interactions, with hadrons in some particle accelerator experiments, or naturally with the matter in cosmic ray interactions. These interactions usually initially produce pi mesons, which often decay to muons.

As in the case of other charged leptons, muons have an associated muon neutrino, denoted by νμ that is not the same particle as electron neutrino and does not participate in similar nuclear reactions.
