Energetics of Charged Pion Decay. Since the charged pions decay into two particles, a muon and a muon neutrino or antineutrino, then conservation of momentum and energy give the decay products definite energies. This contrasts with the three-particle decay of the neutral pion in which the emitted particles have a range of energies and momenta.

The neutral pion decays to two photons (gamma rays) 98.8% of the time. The decay is by the electromagnetic interaction on a time scale of about 10-16 seconds. The positive and negative pions have longer lifetimes of about 2.6 x 10-8 s. The negative pion decays into a muon and a muon antineutrino as illustrated below.

Equation (1) is thus the consequence of two separate equations, one for each decay process, pion decay σ μ = Cp μ, muon decay I = A + Dσ μ ·p e´ Neutral pions decay electromagnetically to photons, by annihilating their valence quark-antiquark pair. Charged pions do not have that option: they have to decay into at least one other charged particle, i.e. an electron or muon. So the expanded question should probably be “why do charged. Continue Reading. Rare decay modes of the pion and muon are an abundant source of information about elementary particles and their interactions. The problems of muon-electron universality, muon number non-conservation and the radiative decay of the pion are discussed.

Calculate the velocity of the decaying pion using the velocity transformation formula. Assume that muon is produced along the direction of pion’s velocity. The only channel left for them to decay is through the weak interaction: they can annihilate into an off-shell \(W\) boson which promptly decays into a charged lepton and a neutrino. From the perspective of the mass the charged lepton can be either an electron or a muon.

I know it has to do with helicity supression, but I can't quite formulate a description of what helicity supression is concisely by reading Thomson's explanation. This is also why the pion prefers to decay to a muon! 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.
