Tau decays
In total, the tau lepton will decay hadronically approximately 64.79% of the time. The branching fractions of the common purely leptonic tau decays are: [3] 17.82% for decay into a tau neutrino, electron and electron antineutrino; 17.39% for decay into a tau neutrino, muon, and muon antineutrino. See more 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 See more The search for tau started in 1960 at CERN by the Bologna-CERN-Frascati (BCF) group led by Antonino Zichichi. Zichichi came up with an idea of a new sequential heavy lepton, now called tau, and invented a method of search. He performed the … See more • Flavour (particle physics) • Generation (particle physics) • Koide formula • Lepton See more The tau is the only lepton that can decay into hadrons – the masses of other leptons are too small. Like the leptonic decay modes of the tau, the hadronic decay is through the See more The tau lepton is predicted to form exotic atoms like other charged subatomic particles.

Tau Decays in the Collinear Limit The dominant decay channels of the ˝are into a single pion, leptons, or into a vector meson resonance. In these channels, ignoring the decays of the vector mesons, the distribution of the nal state momenta can be determined in the collinear limit (i.e. p ˝!1). These results are useful for the validation of ...
