In particle physics, helicity is the projection of the angular momentum onto the direction of momentum. For massless spin-1⁄2 particles, helicity is equivalent to the chirality operator multiplied by $\hbar/2$, so may be used for related chirality questions as well.

How does one experimentally determine chirality, helicity, spin and angular momentum of a fu...
If I've got an instance of a fundamental particle, how can I separate out the measurements of these four quantities?
(I think) I understand the theory behind them, and why the particles in the standa …
