Myon
Myon may refer to: * Myon (Locris), a town in ancient Locris, Greece * Myon, Doubs, a town in France * Myeon (administrative division), in Korea * Muon, a elementary particle In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons. As a c ...

Myon (Locris)
Agia Efthymia (, ) is a village in the regional unit of Phocis, Greece. It is part of the municipality of Delphi, located on the foothill of Mount Giona the highest mountain of Central Greece, in the district of Parnassida in Central Greece. History Classical antiquity The history of Agia Efthymia can be traced back to ancient Greece, when the town was named Myonia and/or Myania. Myonia is attested by classical sources as a ''polis'', thus it must have been a political community, one of the principal of the ancient Greek tribe of Locrians, in the region of Ozolian Locris. Ruins of the ancient defence town walls have been preserved up to now, in and around the village, as well as remains of an ancient cemetery. In 338 BC, Myonia was sacked by Philip II of Macedon along with Amfissa, because Ozolian Locrians had illegally cultivated part of the Crissaean plain which belonged to Delphi. A treaty between Myonia and Hypnia has been published, as well as a decree of Delphi in honor of ...

Myeon (administrative Division)
A ''myeon'', ''myŏn'', ''myon'', or township () is an administrative unit in South Korea similar to the unit of town. Along with town, township is of a county and some cities of fewer than 500,000 population. ''Myeon'' have smaller populations than towns and represent the rural areas of a county or city. Townships are subdivided into villages. The minimum population limit is 6,000. See also *Administrative divisions of South Korea South Korea is made up of 22 first-tier administrative divisions: 6 List of special cities of South Korea#Position in hierarchy and types, metropolitan cities (''gwangyeoksi'' ), 1 List of special cities of South Korea, special city (''teukbyeo ...

Muon
A muon ( ; 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  ''ħ'', 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. The muon is an unstable subatomic particle with a mean lifetime of , much longer than many other subatomic particles. As with the decay of the free 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 t ...
