antiparticules
antiparticle (noun) particle symmetric and opposite an elementary particle, annihilating with the latter producing photons. In 1930, the British physicist Paul Dirac said, in view of theoretical knowledge, that any given particle has a corresponding antiparticle. The antiparticle of the electron was discovered in 1932 by the American physicist Carl Anderson, who called positron. The antiproton was observed in 1955 by the American physicist Owen Chamberlain (b. 1920) and Emilio Segre. It is now known as Dirac’s prediction is correct for all elementary particles. Some elementary particles like the photon, are their own antiparticle. Physicists generally use a bar to represent the antiparticle.
Meaning and uses
Antiparticle – For each type of particle has a corresponding antiparticle type. Thus, the electron is associated with the positron, and quarks, antiquarks. …
antiparticle – Similar to the particles of the material of the same mass but opposite charges
antiparticle – particle that has the same characteristics as an ordinary particle, with the exception of an opposite charge. These are antiparticles of antimatter. The encounter between matter and antimatter annihilation leads to a complete transformation in by two photons.
antiparticle – with particle characteristics (charge, magnetic moment …) opposite to those of the particle considered.
