*[[Antibaryon]]s have opposite charge and quantum numbers to their corresponding [[baryon]]s.
*Studied in high-energy physics experiments to understand [[matter]]-[[antimatter]] symmetry.
: '''Antibaryons''' are affected by the:
:*[[Strong Nuclear Interaction]]
:*[[Weak Nuclear Interaction]]
:*[[Electromagnetic Interaction]]
:*[[Gravitational Interaction]]

===Examples===
*The [[antiproton]] (composed of two anti-up [[quark]]s and one anti-down [[quark]]) is an [[antibaryon]].
*[[Antibaryon]]s are produced in [[Particle Accelerator|particle colliders]].
