antiprotons
Protons' antimatter counterparts
Antiprotons are the antimatter counterparts of protons—identical in mass but with opposite charge.
When an antiproton meets a proton, they annihilate each other, releasing energy.
Antiprotons are produced in particle accelerators and used in physics experiments to study fundamental properties of matter: The team generated antiprotons to test charge-parity symmetry.
