Antiparticle: Each type of matter particle has a corresponding antiparticle.

Each fermion has a corresponding antiparticle.

For every type of matter particle there is a corresponding antiparticle with the same mass and the opposite charge.

Since that time, it has been verified experimentally that every known kind of particle has a corresponding antiparticle.

In this situation the particles and their corresponding antiparticles do not achieve thermal equilibrium due to rapid expansion decreasing the occurrence of pair-annihilation.

To preform a charge conjugation, one would exchange all particles with their corresponding antiparticles.

Every local field both creates particles and annihilates the corresponding antiparticle.

For every kind of particle there is a corresponding antiparticle.

High-precision experiments have been unable to detect any difference between the masses of particles and those of the corresponding antiparticles.

This was the first interpretation and prediction of a particle and corresponding antiparticle.
