Real neutral particle

Real neutral particle

In physics, a real neutral particle is a particle that is its own antiparticle. Examples are the photon, the Z boson, the neutral pion, the hypothetical Higgs boson, and the hypothetical neutralino.

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 electromagnetic 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.
