Each meson has a corresponding antiparticle (antimeson) where quarks are replaced by their corresponding antiquarks and vice-versa.

A photon can also be emitted when a particle and its corresponding antiparticle are annihilated (for example, electronpositron annihilation).

As the radioisotope undergoes positron emission decay (also known as positive beta decay), it emits a positron, an antiparticle of the electron with opposite charge.

Since then, the antiparticles of many other subatomic particles have been created in particle accelerator experiments.

For example, the antiparticle of the electron is the positively charged electron, or positron, which is produced naturally in certain types of radioactive decay.

It also includes the discovery of composite particles and antiparticles that were of particular historical importance.

When a particle and antiparticle scatter, virtual particles can be exchanged in two qualitatively different ways.

The remarkable notion of an antiparticle to each fermion particle e.g. the positron as antiparticle to the electron stems from his equation.

The latter is seen in many processes in which both a particle and its antiparticle are created simultaneously, as in particle accelerators.

Instead of being states with no antiparticle, these are states that are already filled with a negative energy particle.

The antiparticle of the electron is the antielectron, which is nearly always called "positron" for historical reasons.
