[particle physics] Because the eigenvalues of spin with respect to an axis have discrete values, the eigenvalues of helicity are also discrete. For a particle of spin {mvar|S}, the eigenvalues of helicity are {mvar|S}, S − 1}}, ..., − {mvar|S}. The measured helicity of a spin {mvar|S} particle will range from − {mvar|S} to + {mvar|S}....

• (gen phys) The measure of 'twist' an object has; for example, the degree of coiling of a magnetic field. • (part phys) The projection of a particle's spin along its direction of motion. The helicity of a particle is described as being either left- or right-handed depending on whether i...

A property of a moving fluid which represents the potential for helical flow (i.e. flow which follows the pattern of a corkscrew) to evolve. Helicity is proportional to the strength of the flow, the amount of vertical wind shear, and the amount of turning in the flow (i.e. vorticity).

helicity The projection of a particle's spin vector in the direction of its momentum vector, being positive if it points in the same direction, and negative if it points in the opposite direction. Helicity is in effect the handedness, or chirality, of the spin of a particle.
