Introduction toElementary Particle Phenomenology
... All particles either naturally possess or may be assigned an intrinsic parity. In the case of fermions a consequence of the Dirac equation is that any given fermion and antifermion have opposite parities. Since fermion number is conserved (only fermion–antifermion pairs may be created or annihilated ...
