Conservation Laws
Laws
- Baryon number is always conserved
- Lepton muon number is always conserved
- Lepton electron number is always conserved
| Conservation | Laws | Quantum Numbers | Conserved? |
|---|---|---|---|
| Baryon | B | +1/0/-1 | Conserved |
| Charge | Q | +1/0/-1 | Conserved |
| Lepton Number | L\(_{e}\) | +1/0/-1 | Conserved |
| Lepton Muon | L\(_{\micro}\) | +1/0/-1 | Conserved |
| Strangeness | S | +2/+1/0/-1/-2 | Only when produced via the strong force |
\[p + p \to p + p + k^++k^-\]
\(\(k^{-}\to \mu^-+\overline{v_{\mu}}\)\)
B, 0 = 0 0
Q, -1 = -1 0
L\(_{e}\) , 0 = 0 0
L\(_{\mu}\) , 0 = +1 -1
S, -1 = 0 0
Strangeness is different because this interaction is caused by the weak force and is therefore not conserved.
