A chiral phenomenon is one that is not identical to its mirror image (see the article on mathematical chirality). The spin of a particle may be used to define a handedness, or helicity, for that particle, which, in the case of a massless particle, is the same as chirality. A symmetry transformation between the two is called … See more The helicity of a particle is positive (“right-handed”) if the direction of its spin is the same as the direction of its motion. It is negative (“left-handed”) if the directions of spin and motion are opposite.

Something that could overtake a neutrino—say, a speedy photon—would see the neutrino’s helicity flip. But since humans don’t spend a lot of time moving at the speed of light, there is a lot of overlap between helicity and chirality. ...
