   Antiparticles
   Each particle has a partner called an antiparticle. Some properties of the antiparticle will be identical in magnitude but opposite in sign to the particle it is paired with. Examples of such properties are electric charge in the case of the electron and positron, and magnetic moment inthe case of t...

   antiparticles
   Counterparts of ordinary subatomic particles, which have the same mass and spin but opposite charge, magnetic moment, and any other internal attributes (including lepton, baryon, strangeness, and charm quantum numbers). Each particle has a corresponding antiparticle, although certain purely neutral ...

   Antiparticles
   In particle physics every particle with any type of charge or fermion label has a corresponding antiparticle type. Any particle and its antiparticle have identical mass and spin but opposite charges. For example the antiparticle of an electron is a positron It has exactly the same mass as an electro...
