Chiral handedness
WebHandedness refers to two properties of a particle: the direction of its spin and how it relates to the direction the particle is traveling. ... Neutrinos can be left-chiral or right-chiral. … WebAug 21, 2024 · As Wikipedia puts it, "it is determined by whether the particle transforms in a right- or left-handed representation of the Poincaré group." Though terms like "left-chiral" and "right-chiral" might be more suitable, people usually also use the terms left-handed and right-handed when talking about chirality.

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 parity transformation. Invariance under parity transformation by a Dirac fermion is called chiral symmetry. WebThe explanation is simple--- all particles we can see are chiral, they have only one handedness, because if they had both handedness, they could get a mass, and generically, that mass would be of order of magnitude the Planck mass. We live at energy scales which are teeny compared to the Planck mass, so we can only see massless …
