antiparticle

1. A subatomic particle, such as a positron, antiproton, or antineutron, having the same mass, average lifetime, spin, magnitude of magnetic moment, and magnitude of electric charge as the particle to which it corresponds but having the opposite sign of electric charge, opposite intrinsic parity, and opposite direction of magnetic moment. See Table at subatomic particle.

2. A subatomic particle not found in ordinary matter.

3. A subatomic particle identical to another subatomic particle in mass but opposite to it in electric and magnetic properties (as sign of charge) that when brought together with its counterpart produces mutual annihilation.
