Tau (particle) Another one is an onium atom called "true tauonium" and is difficult to detect due to tau's extremely short lifetime at low (non-relativistic) energies needed to form this atom. Its detection is important for quantum electrodynamics. Tau (particle) 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. Together with the electron, the muon, and the three neutrinos, it is a lepton. Like all elementary particles with half-integer spin, the tau has a corresponding antiparticle of opposite charge but equal mass and
Angus (given name) dialects underwent changes which included the loss of the final syllables and unstressed vowels, which affected "*Oinogustos" thus: "*Oin<del>o</del>gust<del>os</del>". Angus (given name) Angus is a masculine given name in English. It is an Anglicised form of the Irish and Scottish Gaelic "Aonghas", which is composed of Celtic elements meaning "one", and "choice".
