WebHelicity and Chirality for massive particles: So far we considered chirality/handedness for massless fermions. However, the 'chirality properties' of massive fermions are also of interest. The reason for this is that most particles are massive and the charged current weak interaction couples to left handed (negative chirality) spinors (V-A theory).
