WebDec 29, 2024 · The muon and tau are unstable decaying with the weak interaction. The muon decays to electron and neutrinos, because its mass is too low to have an emergent pi0. The tau has high enough mass to decay into hadrons, again through the weak interaction. So experimentally they are very much different.

WebJun 8, 2024 · The ATLAS Collaboration has just released a measurement of the cross section of the Higgs boson decaying to a pair of tau leptons, the heaviest known leptons. The new result is an unambiguous observation of this decay with a significance of 6.4 standard deviations.
WebThe time constant τ is the amount of time that an exponentially decaying quantity takes to decay by a factor of 1/e. Because 1/e is approximately 0.368, τ is the amount of time that the quantity takes to decay to approximately 36.8% of its original amount.
