In particle physics, a lepton is an elementary particle of half-integer spin (spin 1 / 2 ) 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 .
A muon (/ ˈ m (j) uː. ɒ n / M(Y)OO-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 spin-1/2, but with a much greater mass.
A bronze mite, also known as a Lepton (meaning small), minted by Alexander Jannaeus, King of Judaea, 103–76 BC and still in circulation at the time of Jesus [1]. The lesson of the widow's mite or the widow's offering is presented in two of the Synoptic Gospels (Mark 12:41–44 and Luke 21:1–4), when Jesus is teaching in the Temple in Jerusalem.
The lepton, plural lepta (Greek: λεπτόν, λεπτά), is the name of various fractional units of currency used in the Greek-speaking world from antiquity until today. The word means "small" or "thin", and during Classical and Hellenistic times a lepton was always a small value coin, usually the smallest available denomination of another ...
The water-based detectors Kamiokande II and IMB detected 11 and 8 antineutrinos (lepton number = −1) of thermal origin, [104] respectively, while the scintillator-based Baksan detector found 5 neutrinos (lepton number = +1) of either thermal or electron-capture origin, in a burst less than 13 seconds long. The neutrino signal from the ...
The tau (τ), also called the tau lepton, tau particle or tauon, is an elementary particle similar to the electron, with negative electric charge and a spin of 1 / 2 .Like the electron, the muon, and the three neutrinos, the tau is a lepton, and like all elementary particles with half-integer spin, the tau has a corresponding antiparticle of opposite charge but equal mass and spin.
In one type of charged current interaction, a charged lepton (such as an electron or a muon, having a charge of −1) can absorb a W + boson (a particle with a charge of +1) and be thereby converted into a corresponding neutrino (with a charge of 0), where the type ("flavour") of neutrino (electron ν e , muon ν μ , or tau ν τ ) is the same ...
