antiparticle; the symmetric counterpart (e.g., positron, antiproton) to an ordinary particle
formalA particle physics term. An antiparticle has the same mass, spin, and lifetime as its corresponding ordinary particle, but opposite charge and magnetic moment orientation. When a particle and its antiparticle meet, they annihilate, producing other particles like photons.
