## Main Question or Discussion Point

Hi forum,

The weak force vertex factor is γ

the axial component only couples to left handed fermions? Does the vector component

couple to both left and right-handed fermions?

Thanks, Mark

^{u}(1-γ^{5}). Am I right thatthe axial component only couples to left handed fermions? Does the vector component
