Chirality is defined through the ±1 eigenvalue under action of γ^5 on ψ, a Dirac field thus projected into its left- or right-handed component by the projection operators (1−γ^5)/2 or (1+γ^5)/2 on ψ. For massless particles (only!) chirality coincides with [helicity], a notion which is frame-dependent, and hence ambiguous for massive particles. Avoid using the [helicity] tag instead: the projectors *must* be implied.

Why do chiral objects only come in pairs?
My question arise and is connected to the "strange" fact
that many things seem to come in pair or in number of two
similar "objects".
Why are there chiral "pairs" and not groups of 3,4, or more? What …
