Key Stage 5
Meaning
An antibaryon is a hadron consisting of three antiquarks.
About Antibaryons
- The antiparticle counterpart to baryons like protons and neutrons.
- Antibaryons have opposite charge and quantum numbers to their corresponding baryons.
- Studied in high-energy physics experiments to understand matter-antimatter symmetry.
- Antibaryons are created in high-energy particle collisions and cosmic rays.
- Antibaryons annihilate with baryons producing high-energy gamma rays.
The study of antibaryons helps in understanding the fundamental forces in nature.
- Antibaryons are affected by the:
| Antibaryon | Antiquark-composition | Charge/e | Strangeness | Baryon Number | Lepton Number |
| \(\bar{u}\bar{u}\bar{d}\) | \(Q=-1\) | \(S=0\) | \(B=-1\) | \(L=0\) | |
| \(\bar{u}\bar{d}\bar{d}\) | \(Q=0\) | \(S=0\) | \(B=-1\) | \(L=0\) |
Examples
- The antiproton (composed of two anti-up quarks and one anti-down quark) is an antibaryon.
- Antibaryons are produced in particle colliders.
