noun
- Plural of helicity; the property of a particle or wave related to the direction of its spin or rotation relative to its direction of motion.
Usage: physics; technical
Examples
- In particle physics, helicities describe how elementary particles spin as they move through space.
- The helicities of photons determine their polarization states.
- Physicists measure the helicities of neutrinos to understand their fundamental properties.
- Different helicities of the same particle can have different interaction rates with matter.
