Tau decay modes

http://www.astrostatistics.psu.edu/datasets/R/html/boot/html/tau.html WebApr 8, 2024 · The decay width $\Gamma=K m^5 $ is an approximation that holds when all final state particles are much lighter than the decaying particle. For the muon, there is only one decay mode(the muon is not massive enough to create the lightest meson). So $\Gamma_\mu\approx K m_\mu^5 $.The tau has two leptonic decay modes, and one …

WebFurthermore, an upgraded reconstruction for hadronic tau decays is presented that allows for the determination of decay modes and of the four-momenta of the individual hadrons from these decays. Five decay modes are distinguished, and the classification is accurate for 75% of the hadronic tau decays in Z=!˝˝events.

WebTau decay modes. The tau lepton has a very short lifetime of about 290 femtoseconds after which it decays into other particles. With a probability of about 20% each, the tau lepton decays into a muon or an electron and two neutrinos. All other decay modes consist of a combination of hadrons such as pions and kaons and a single neutrino. WebMar 14, 2024 · python求矩阵的特征值和特征向量.
