Chirality vs helicity
Did you know?
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. http://www.quantumfieldtheory.info/Chiralityvshelicitychart.htm

For free massless spinors, the spin eigenstates are also helicity eigenstates and chirality eigenstates. In other words, the Hamiltonian for the massless Dirac equation commutes with the operators for chirality, γ5, helicity, S⃗·p⃗ ...
WebJul 26, 2008 · 8. 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. 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. …
