Real neutral particle : ウィキペディア英語版 | Real neutral particle
In particle physics, a real neutral particle is an elementary particle that is its own antiparticle. Known examples include photons, Z bosons, Higgs bosons, and neutral pions; along with the hypothetical neutralinos, sterile neutrinos, and gravitons (if they exist). The electromagnetic charge, weak charge, and strong charge of such a particle must be the same as that of its antiparticle. In the case of the electric and strong charges, this implies that the charge must be zero. For a spin-1/2 particle such as the (hypothetical) neutralino, being a real neutral particle means being a Majorana fermion. * http://www.worldscinet.com/ijmpe/13/1302/S0218301304002272.html
