WebThe tau neutrino or tauon neutrino is an elementary particle which has the symbol ν τ and zero electric charge.Together with the tau (τ), it forms the third generation of leptons, hence the name tau neutrino.Its existence was immediately implied after the tau particle was detected in a series of experiments between 1974 and 1977 by Martin Lewis Perl with his … Web2 days ago · Caption: In the brains of mice treated with the new peptide (two right panels), many fewer Tau proteins (stained purple) are seen in the top right.

WebSep 1, 2008 · The status of the experiment on the precise τ lepton mass measurement running at the VEPP-4M collider with the KEDR detector is reported. The mass value is evaluated from the τ + τ − cross section behavior around the production threshold. The preliminary result based on 15.2 pb −1 of data is m τ = 1776.69 −0.19 +0.17 ± 0.15 MeV. 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 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 the tau's case, this is the "antitau" (also called the positive tau). Tau particles are denoted by the symbol …
