Every particle has an antiparticle. An Antiparticle is defined as a particle that has mass, spin, charge and all other properties that are opposite of the sign of any specific elementary particle.
Antiparticle of proton
- Antiparticle of proton is antiproton with a mass of 938.257 MeV with negative charge.
- These antiprotons are created by using particle accelerator.
- The accelerator runs at a very high speed such that the particles attain the speed of light resulting in generation of antiprotons.
- But these antiprotons when come in contact with the walls of the particle accelerator decay.
