Cosmic Rays and Measurement of the Lifet: Alcocer Giovanni
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 2003-05-01 · 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 . Energetics of Charged Pion Decay.

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. Pion Decay!

Need the same three-body kinematics. Form Factors A big difference is that the decaying muon is a fundamental particle, while the weak decay of a neutron (or any other hadron) arises from the the decay of one of it’s constituent quarks. Free muon decay Theoretical vs experimental accuracy How to improve the theory Lepton-flavor violation: searches Background: bound muon decay Modification of the electron spectrum by binding Precise description of the spectrum.
We will see later that the decay with a muon is preferred.

It therefore lacks the Energy of a Muon. To become a Muon it would need to draw Energy from the Aether.

The asymmetry in the muon decay correlates the positron emission and the muon spin directions. The simplest example is when the spin direction of all muons remains constant in time after implantation (no motion). 1.- Pion Decay to Muon.

(b) The muon is unstable, with a lifetime τ 1 in the pion's rest frame. Find the lifetime t 0 of the muon in its own rest frame. Solution: Concepts: Relativistic "collisions", energy and momentum conservation; Reasoning: The decay of a particle is a relativistic problem. A neutral pion from this interaction decays in about 10 16 s into two photons, which create an electro-magnetic shower that is di cult to detect on the ground and is not considered in this experiment. There are two possibilities for a charged pion from the shower. Given enough time, the pion will decay to a muon and a neutrino.
For massive particles the handedness can be flipped by a boost! For a massive particle the forbidden helicity states are only suppressed by: This is also why the pion prefers to decay to a muon! Pion and muon decay in flight PEN technical note Where B(ˇ!e ) is the ˇ e2 branching ratio. While at rst glance this may appear to be a low rate, it is to be compared to the ˇ e2 yield integrated over the pion gate T, so it represents a ˘0.5% correction.
Pions. 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.
