Baryons
BARYONS ARE A TYPE OF HADRON
Baryons
- Include protons, neutrons and sigma
- Made of three quarks
- Baryons have anti-particles
- All baryons have a baryon number, which is a quantum number and must be conserved.
Baryon Numbers
- Baryons or normal matter have a baryon nyumber of +1
- Baryons of antimatter have a baryon number of -1
- Non-baryons have a baryon number of 0
- Baryon number can be written as "B"
Stability
- Almost all baryons are unstable and will decay over time. The only non-decaying baryon is the proton.
- Neutrons decay via beta decay \(\(n \to p+e^-+(anti){v_{e}}\)\)
- During a decay, the baryon number is always conserved, as shown in the equation above. \((+1 \to +1 + 0 + 0)\)
