  • (n) an unstable negatively charged proton; the antiparticle of a proton


  1. One of physics' most exciting recent discoveries is the antiproton.
  2. The antiproton, having lost its negative charge and received nothing in return, also became a chargeless particle, but it did not become a normal neutron.
  3. Proton-antiproton collisions entail more energy than electron- positron collisions and thus are more likely to generate previously undiscovered particles.
