Kinds of baryon :

• antineutron (6 facts) - The antiparticle of a neutron. A neutron and antineutron both have the same mass and zero electric charge, but can be differentiated by their interactions: a neutron and an antineutron can annihilate into gamma rays, while two neutrons cannot.
• antiproton (7 facts) - The antiparticle of a proton, identical in mass and spin but of opposite (negative) charge.
• hyperon (4 kinds, 17 facts) - Baryons heavier than the neutron (this term is seldom used today). They have non-zero strangeness. Free hyperons are unstable and decay into end products, one of which is a proton.
• nucleon (2 kinds, 33 facts) - The generic name for the proton and the neutron.
