Helicity
Reference
Definition
Helicity is a measure of how vortex lines in fluid flow, or field lines in magnetic or electromagnetic fields, twist, kink, link, or coil around one another. In physics, it can also mean the component of a moving particle’s quantized spin along its direction of motion.

Meaning of helicity
Helicity describes the extent to which vortex lines or magnetic and electromagnetic field lines twist, kink, link, or coil around one another. It can also refer to the quality of being helical.
Helicity in particle physics
In particle physics, helicity is the quantized spin component of a moving particle measured along the direction of its motion.
