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. But since humans don ... WebBoth the left and right hand are chiral (ky-ral) and show chirality. Chiral is derived from the Greek word cheir, which means “hand”, and chirality means “handedness”.
