By … WebAug 15, 2024 · Therefore, acting the helicity operator on the Dirac spinors gives the eigenvalues $\pm 1/2$. The two possible helicity states for a spin 1/2 fermion are termed right-handed and left-handed helicity states. This is why we have four independent basis states, two for particle and two for antiparticle solutions. P.S.
