Antiproton

An antiproton is a subatomic particle that is the counterpart of a proton, which is found in the nucleus of atoms. While a proton has a positive electric charge, an antiproton has a negative charge. Both particles are types of baryons, which are made up of quarks. Antiprotons are produced in high-energy processes, like cosmic rays or particle accelerators. They are significant in physics for studying antimatter, which has the same mass as regular matter but opposite charge and other properties. Understanding antiprotons can help scientists explore fundamental questions about the universe's composition.
