• Helicity (particle physics) — In particle physics, helicity is the projection of the spin vec S onto the direction of momentum, hat p ::h = vec Scdot hat p,qquad hat p = vec p / |vec p|Because the spin with respect to an axis has discrete values, helicity is discrete, too.… …   Wikipedia

• Chirality (physics) — A chiral phenomenon is one that is not identical to its mirror image (see Chirality). The spin of a particle may be used to define a handedness (aka chirality) for that particle. A symmetry transformation between the two is called parity.… …   Wikipedia
