In experiments with polarized beams of particles, I suppose one knows the spin orientation probabilities of those particles, is that the case?
When physicists make experiments with polarized beams of unstable particles, how do they treat spin in a decay of such a polarized particle? If the spin polarization vector of particle before decay is known, can they determine spin polarization of decay products?
For example in a polarized beam of muons [itex]\mu^+[/itex] with a given spin polarization [itex]{\bf S}=(S_x,S_y,S_z)[/itex] decays into three particles, e.g. [itex]\mu^+\to\nu_\mu e^+\bar{\nu}_e[/itex], could the polarization vector of positron be determined?
Or maybe this image is totally wrong!?
