Are Antiparticles and Antimatter?

Antiprotons, as the name implies, are protons with a negative charge. These antimatter particles (which are called "antiparticles") have been generated and studied at huge particle accelerators such as the Large Hadron Collider operated by CERN (the European Organization for Nuclear Research), NASA stated.

Are antiparticles and antimatter the same?

Antimatter is a material composed of so-called antiparticles. ... But its antiparticle, called a positron, has the same mass but a positive charge. When a particle and its antiparticle meet, they annihilate each other – disappearing in a burst of light.

Is positron an antimatter?

The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. The positron has an electric charge of +1 e, a spin of 1/2 (the same as the electron), and has the same mass as an electron. When a positron collides with an electron, annihilation occurs.
