An analytical approach to the problem is derived for a The autodynamics equations are explained, and their application to muon decay is analyzed. Autodynamics can explain the results obtained at SLAC and CERN. The author concludes that the problem of muon and pion decay remains to be resolved by the experimenters. Key words: autodynamics equations, muon decay, experiments of CERN and SLAC. 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.

Summary:: I am computing the decay rate for the pion into a muon and anti-muon neutrino but I do not get the desired expression *, so I would like to discuss the calculation I am studying the following process: pion decays (mediated by the charged ##W## boson) into a muon and anti-muon neutrino (i.e. ##\pi^- \to \mu + \bar{ u}_{\mu}##). Handedness is a well defined property for massless particles (coincides with helicity). For massive particles the handedness can be flipped by a boost!

Find the kinetic energy and momentum of the muon and the neutrino in MeV. Solution by Michael A. Gottlieb: (I choose units such that c = 1, and assume that me = 0.511MeV.) Since the pion is at rest conservation of momentum dictates that the momenta of the Pion at rest decay into muon and neutrino.

Studies of rare kaon decays are entering an interesting new phase wherein they … 1990-01-01 1. to measure the muon lifetime, i.e. the average duration of the life of a muon in its rest-frame, 2. confirm that there is forward-backward asymmetry in the emission of the positrons with respect to the muon spin direction (and therefore parity violation in the decay).

Charged pions (π+ and π−) decay into positive and negative muons that decay in turn into relativistic electrons and positrons. Neutral pions (π0) decay almost  Pions that decay give rise to the muon and neutrino components which easily penetrate the atmosphere. Although the mean life of muons at rest is short,  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  Pion decay.

So the expanded question should probably be “why do charged. Continue Reading. The pion decays into a muon and a neutrino which have opposite momenta in the center-of-mass frame. The decay is isotropic and the muon has the energy–momentum vector v μ 0 =m π κ (1−κ) cos u (1−κ) sin u in the direction of angle u .
