annihilation A reaction between an elementary particle and its antiparticle in which the two particles disappear and photons or other particles and antiparticles are created; energy and momentum are conserved. An electron and a positron, for example, interact and produce two gamma-ray photons. Hadrons, such as the proton and the antiproton, also undergo annihilation, as do quarks and antiquarks.annihilation[ə‚nī·ə′lā·shən] (particle physics) A process in which an antiparticle and a particle combine and release their rest energies in other particles. annihilation
