Pion muon
WebThe primary decay mode of a Pion, with probability 0.999877, is a purely Leptonic decay into an anti-Muon and a Muon Neutrino. The second most common decay mode of a Pion, with probability 0.000123, is also a Leptonic decay into an Electron and the corresponding Electron anti-Neutrino. This "electronic mode" was discovered at CERN in 1958. WebSo the mediator of the strong force was thought to be a pion and the model worked pretty well. (In the 1930s, people were also confusing muons and pions in the cosmic rays, using names that sound bizarre to the contemporary physicists' ears - such as a mesotron, a hybrid of pion and muon, but that's another story.)

WebThe momentum of the muon from pion decay at rest is p μ + = (29.792 00 ± 0.000 11) MeV/c, cf. Table 1. As can be seen, the contributions from the uncertainties of the … WebMuons are produced artificially from pions formed by the collision of energetic protons with low-Z targets. The pions decay with a lifetime of 26 ns: [2] The neutrino, ν, has negative helicity (angular momentum antiparallel to linear momentum), so from conservation laws the muon must also have negative helicity.
Web2. a pion at rest can decay into a muon and a neutrino. Conservation of energy and 3-momentum require. Conservation of energies. E π = E μ + E ν. Conservation of momentum. P π = P μ + P ν. but. P π = 0. WebEach pion consists of a quark and an antiquark and is therefore a meson. Pions are the lightest mesons and, more generally, the lightest hadrons. They are unstable, with the charged pions ... Charged pions most often decay into muons and muon neutrinos, while neutral pions generally decay into gamma rays.
WebA titanium target 1mm thick and 10mm long is dipped 2-5mm into the halo of the ISIS proton beam at 1Hz, providing the initial source of pions. The target is dipped at ~ 800MeV. This provides pions... http://hitoshi.berkeley.edu/129a/cahn-goldhaber/chapter2.pdf
WebThe only options are photons (massless & neutral), neutrinos (neutral and near-as-dammit massless), and electrons & muons (charged and massive — the muon is not far off the pion mass). Neutral pions decay electromagnetically to photons, by annihilating their valence quark-antiquark pair.
