Right handed helix vs left
WebWhen using this convention, left- or right-handedness is determined by pointing one's left or right thumb away from the source, in the same direction that the wave is propagating, and matching the curling of one's … WebChirality for a Dirac fermion ψ is defined through the operator γ 5, which has eigenvalues ±1; the eigenvalue's sign is equal to the particle's chirality: +1 for right-handed, −1 for left-handed. Any Dirac field can thus be projected into its left- or right-handed component by acting with the projection operators ½(1 − γ 5) or ½(1 ...
