selfantiparticles
Selfantiparticles are a hypothetical type of elementary particle that is its own antiparticle. This means that the particle and its antiparticle are identical in terms of mass and charge, but would differ in some other quantum property, if such a distinction could even be made. The most well-known candidates for selfantiparticles are the neutrino and the photon.
Neutrinos are electrically neutral and have extremely small masses. If a neutrino were its own antiparticle,
Photons, the quanta of the electromagnetic field, are also electrically neutral and massless. They are currently
The theoretical exploration of selfantiparticles is an active area in particle physics, as confirming their existence
