WebIn the ﬁrst section, we explore the topics of chirality and helicity. Chirality is an inherent property of particles, whereas helicity of a particle depends on the particle’s momentum. … WebNeutrinos can be left-chiral or right-chiral. Physicists have seen only neutrinos born in a left-chiral state, and only right-chiral antineutrinos. So chirality is built in, but helicity is a matter of perspective. Something that could overtake a neutrino—say, a speedy photon—would see the neutrino’s helicity flip.

WebAs nouns the difference between chirality and helicity is that chirality is the phenomenon, in chemistry, physics and mathematics, in which objects are mirror images of each other, but are not identical while helicity is the quality of being helical. http://www.quantumdiaries.org/2011/06/19/helicity-chirality-mass-and-the-higgs/

Helicity is the projection of the spin on the momentum direction. Chirality refers to the transformation laws, or the representation of the Lorentz group the particle belongs to. If a particle is massless, the situation is simple : helicity can only take the two extreme +S and -S, and all observer agree on that.
