The next question has to do with where muons come from. Muons come from pion decay, which in turn are generated from high-energy proton for a given energy, electron has higher velocity than muon and so less likely to have “wrong” helicity. P461 - particles IV. 4. Pion Decay Kinematics.

Pion decay to muon

Previous article. in issue. This analyst believes that the problem of muon and pion decay remains in the hands of the experimenters, especially those of Refs. 6, 9, and 10 because they have the data and the equipment that could determine whether the electron and positron are really those particles, or if they are electromuons, or electromuons with subsequent decay as shown in Fig. 3. @article{osti_934998, title = {Isochronous pion decay channel for enhanced muon capture}, author = {Yoshikawa, C and Ankenbrandt, C and Neuffer, D and Popovic, M and Yonehara, K and /Fermilab and Derbenev, Y and / /Jefferson Lab and Abrams, R J and Cummings, M A.C. and Johnson, R P and /MUONS Inc., Batavia}, abstractNote = {Intense muon beams have many potential applications, including See the answer.

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.

Hint: relativistic momentum is conserved. Relevant Equations: See below Pion at rest decay into muon and neutrino. a pion at rest can decay into a muon and a neutrino. Conservation of energy and 3-momentum require.

Intense muon beams have many potential applications, including neutrino factories and muon colliders. However, muons are produced in tertiary beams into a diffuse phase space. To make useful beams, the muons must be rapidly cooled before they decay.

An efficient collection of muons is a crucial task for machines such as neutrino factories or muon colliders. The definition of the beam emittance and the determination of the capture efficiencies both in transverse and longitudinal spaces is made difficult by the transition from the pion to the muon beam through the decay process. electron/muon spinor from the kinematics of pion decay at rest Hence because the electron mass is much smaller than the pion mass the decay is heavily suppressed.

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.
