  antipartticle \an`ti*part"ti*cle\
     ([a^]n`t[i^]*[aum]r"t[i^]*k'l), n. (Physics)
     A fundamental particle which has the same mass as one of the
     common fundamental particles, but which has an opposite
     charge, and for which certain other of the properties (e. g.
     baryon number, strangeness) may be opposite to that of the
     normal particle. The antiparticle to an electron is called a
     {positron}; the antiparticle to a proton is called an
     {antiproton}; the antiparticle to a neutron is called an
     {antineutron}. When a particle and its corresponding
     antiparticle collide, they typically annihilate each other
     with the production of large quantities of energy, usually in
     the form of radiation. The interaction of a proton and
     antiproton cause annihilation with production of mesons.
