Antiparticle
Definition
An elementary particle that has exactly the same mass, lifetime, and spin as a corresponding particle of ordinary matter, but whose electric charges, quantum numbers, and magnetic moments have opposite mathematical signs. Upon direct contact between a particle and an antiparticle, the structural phenomenon of mutual annihilation occurs, converting their entire mass into energy in the form of high-frequency photons.
