A muon is an unstable elementary particle that readily undergoes decay and has a lifetime of 2.2 microseconds when at rest. According to the special theory of

Clear signature for CP violating 2 pion decay : + and – track, Minv^2 = (p1+p2)^2 ~ MK^2, sum of 3 momenta parallel to beam p1. Result 2 pion peak Background. CP is not good symmetry for all weak decays After the decay channel, the muon beam has larger transverse and longitudinal emittances compared with the initial pion beam. The system is designed to accept the geometrical transverse emittance Both positive and negative muons can be produced in relatively large quantities from the decay of pions and kaons resulting from proton interactions with targets at energies beyond several hundreds of megaelectron-volts. This is a weak decay of the strange quark. It is an allowed diagonal change between quark generations.

The lifetime of these particles is to be determined from their decay time  A pion (π) decays at rest into a muon (μ) and a neutrino (ν).

We have measured the momentum of muons from the decay π + → μ + ν μ at rest to be p μ + = 29.79207±0.00012 MeV/c. This result leads to a laboratory upper 

This contrasts with the three-particle decay of the neutral pion in which the emitted particles have a range of energies and momenta. 1.- Pion Decay to Muon. We start by supposing that the Pion is at rest, even though a residual energy appears at the end 2.- Muon Decay to Electron. The Electron momentum will be absorbed by the Muon “container” and the Electron will be 3.- Pion and Muon decay in motion. We suppose here that The primary decay mode of a pion, with a branching fraction of 0.999877, is a leptonic decay into a muon and a muon neutrino : The second most common decay mode of a pion, with a branching fraction of 0.000123, is also a leptonic decay into an electron and the corresponding electron antineutrino. A pion at rest (m = 270 me) decays to a muon (m = 206 me), and an anti neutrino (mv = apx.

It therefore lacks the Energy of a Muon. To become a Muon it would need to draw Energy from the Aether. To form Electrons and Neutrinos, it does not need to do that. Whereas the muon is uninfluenced by the strong force that works inside the nucleus, the pion plays a role in binding protons with neutrons. This means that high-energy muons can penetrate far into The pion has J=0, so the µ+ and νhave the same helicities: The decay to an electron and a neutrino is helicity suppressed R= Γ(π→ eν) Γ(π→ µν) = m2 e m2 µ 1 (1−m2 µ/m2π)2 = 1.275× 10−4 Experimental result proves V−Atheory of weak interactions: R= (1.267±0.023) ×10−4 4 The same nuclear reaction described above (i.e.
