Majorana fermion

In particle physics, a Majorana fermion is a fermion which is its own anti-particle.

No Majorana fermions are known in nature. The neutrino might be a Majorana fermion or it might be a Dirac fermion. If it is a Majorana fermion, then neutrinoless double beta decay is possible; experiments are underway to search for this.

The hypothetical neutralino of supersymmetric models is a Majorana fermion.
