Dirac fermion
In physics, a Dirac fermion is a spin-½ particle which is different from its antiparticle. A vast majority of fermions fall under this category.
Description
In particle physics, all fermions in the standard model have distinct antiparticles and hence are Dirac fermions. They are named after Paul Dirac, and can be modeled with the Dirac equation.A Dirac fermion is equivalent to two Weyl fermions. The counterpart to a Dirac fermion is a Majorana fermion, a particle that must be its own antiparticle.
