In particular, the neutrinos should should have been radiating electron-positron pairs.
FORBES: More Evidence Against Faster Than Light Neutrinos
The detector allows the machine's operators to work out which particles have been created by the electron-positron collisions, and to follow their patterns of decay.

This creates, as it were, electron and positron shadows.

So for every proton there is an anti-proton, and for every electron there is an anti-electron, or positron.

The AMS paper will report the positron-electron ratio in the mass range of 0.5 to 350 Gigaelectronvolts.

The result is that the electron shadow and the positron shadow are separated.
Within the limits of accuracy of the experiment, positron spin-flipping seems to happen at the same frequency as electron spin-flipping.
