WebQuestions tagged [chirality] 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 ... WebThe CHIROBIOTIC TAG is a variation of CHIROBIOTIC T.
