noun
- A hypothetical elementary particle that is the supersymmetric partner of the photon, predicted by supersymmetry theory in particle physics.
Usage: physics; theoretical; not yet experimentally confirmed
Examples
- Physicists search for evidence of the photino in high-energy collision experiments.
- The photino is one of many particles predicted by supersymmetric extensions of the Standard Model.
- If supersymmetry is correct, the photino would be a fundamental constituent of dark matter.
- The mass and interaction properties of the photino remain unknown.
