electron antineutrinos, muon neutrinos and muon antineutrinos - produced in code to calculate the contribution due to pion decays in the Galactic plane.

To form … 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 neutral pion \(\pi^0\)is the lightest meson and therefore cannot decay into another meson. Because of its spin \(S=0\)it cannot decay through a virtual photon to an electron-positron pair. It decays to two photons. The charged pions \(\pi^+,\pi^-\)are the lightest states with quarks of different flavours.

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. hadron-hadron impacts to produce pion beams, which then quickly decay to muon beams over short distances) is used by particle physicists to produce muon beams, such as the beam used for the muon g−2 experiment. The neutral pion \(\pi^0\)is the lightest meson and therefore cannot decay into another meson.

Charged pions do not have that option: they have to decay into at least one other charged particle, i.e. an electron or muon.

We will see later that the decay with a muon is preferred. This means a proton can decay into a positron and a neutral meson (like a pion), a muon and a neutral pion, or an antineutrino and a positively charged meson. The muon spin motion may be measured over a time scale dictated by the muon decay, i.e. a few times τ μ, roughly 10 µs. The asymmetry in the muon decay correlates the positron emission and the muon spin directions.

Fermi National Accelerator Laboratory (Fermilab) Positively charged pions were stopped in a high -purity germanium detector, and the energies of the muons resulting from the decay pi^+ to mu^+ + nu _{mu} were determined. Owing to the long rise time of the pulses from the detector, a pulse-sampling scheme was used to distinguish the pulse due to the stopping pion and from that due to the decay muon.
