The difference between the neutrino and anti-neutrino is the "helicity",
which is the projection of the particle spin on its direction of motion. As
I recall (I've got a 50-50 chance of being correct on this one), the
neutrino has a left-handed helicity while the anti-neutrino has a
right-handed helicity.

What is the difference between a neutrino and an anti-neutrino other than
one goes with beta+ decay and the other goes with beta- decay?
