| By the end of 1932, however, Carl Anderson in the United States had discovered the first antiparticle the positron, or antielectron. |
| The antiparticle of an electrically neutral particle may be identical to the particle, as in the case of the neutral pi-meson, or it may be distinct, as with the antineutron. |
| The emission of the electron's antiparticle, the positron, is also called beta decay. |
| A virtual particle or antiparticle may be captured by the black hole's gravity. |
| In particular, every type of particle of which matter is composed has an equal and opposite antiparticle composed of antimatter. |
| As every schoolboy knows, if you bring a particle and an antiparticle together, they annihilate each other in a burst of energy. |
