physics, a lepton is an elementary particle of half-integer spin (spin ⁠1/2⁠) that does not undergo strong interactions. Two main classes of leptons exist:...

physics, lepton number (historically also called lepton charge) is a conserved quantum number representing the difference between the number of leptons and...

The tau (τ), also called the tau lepton, tau particle, tauon or tau electron, is an elementary particle similar to the electron, with negative electric...

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...

The Standard Model counts six flavours of quarks and six flavours of leptons. They are conventionally parameterized with flavour quantum numbers that...

cosmological models of the Big Bang, the lepton epoch was the period in the evolution of the early universe in which the leptons dominated the mass of the Universe...

Quarks & Leptons is the first EP by Oxide & Neutrino, released on 15 December 2013. It is the follow-up to their third album, 2nd Chance, released in...

During the lepton epoch the temperature of the universe was still high enough to create lepton–anti-lepton pairs, so leptons and anti-leptons were in thermal...

charged leptons (electron, muon and tau lepton) to the gauge bosons are expected to be identical, with the only difference emerging from the lepton masses...

particle physics. Each generation contains two types of leptons and two types of quarks. The two leptons may be classified into one with electric charge −1...

Fautor lepton is a species of sea snail, a marine gastropod mollusk, in the family Calliostomatidae within the superfamily Trochoidea, the top snails,...

spin-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...

neutrino, ν τ Each flavor is associated with the correspondingly named charged lepton. Although neutrinos were long believed to be massless, it is now known that...

Sterile neutrinos (or inert neutrinos) are hypothetical particles (neutral leptons – neutrinos) that interact only via gravity and not via any of the other...

Lepton is a village near Huddersfield in the parish of Kirkburton, in the Kirklees district of West Yorkshire, England. It is 4.25 miles (7 km) to the...

created with a specific lepton family number ("lepton flavor": electron, muon, or tau) can later be measured to have a different lepton family number. The...

The quark–lepton complementarity (QLC) is a possible fundamental symmetry between quarks and leptons. First proposed in 1990 by Foot and Lew, it assumes...

(Greek lepta) are together worth a quadrans, the smallest Roman coin. A lepton was the smallest and least valuable coin in circulation in Judea, worth...

quantum number which is the difference between the baryon number (B) and the lepton number (L) of a quantum system. This quantum number is the charge of a global/gauge...

produced an asymmetry between leptons and antileptons in the very early universe, resulting in the present-day dominance of leptons over antileptons. In the...
