Positron decay direction from muon

[QUOTE="Malamala, post: 6412031, member: 649307"] Thank you so much for this! The slide 6 illustration is useful, however I am not totally clear I understand. In the upper illustration, it is clear why the spin and momenta are the way they are, as there is no other way. But why does the configuration in the bottom plot has to be like that? Assuming helicity and chirality eigenstates are the same, can't we switch the position of ##e^+## and ##\bar{\nu}_\mu##, and still conserve the overall spin? In that case the positron would be emitted in the opposite direction from the muon spin. [/QUOTE]
