[6] [7] The screw axis or the Dn, or Cn principle symmetry axis is considered to be the axis of chirality. Some sources consider helical chirality to be a type of axial chirality, [7] and some do not.

WebMay 31, 2024 · It also turns out that for massless particles chirality and helicity are the same, indeed also helicity flips under space reflections, because momentum is a polar and angular momentum an axial vector, i.e., ##\vec{J} \cdot \vec{P}## is a pseudo scalar under space reflections.
