antiparticle 的定义
Physics.
- a particle all of whose properties, as mass, spin, or charge, have the same magnitude as but, where appropriate, the opposite sign of a specific elementary particle; neutral pions, photons, and gravitons are considered to be their own antiparticles: The positron is the antiparticle of the electron.Compare antimatter, annihilation.

- Physicists would go on to discover many other antiparticles — all of which are identical to their matter partners except for an opposite electric charge — including the antiproton in 1955.
- An imbalance between two types of antiparticles that seethe within the proton is even wonkier than previously thought, a new measurement indicates.
- Positronium is composed of electron and its antiparticle, a positron.
