Key Stage 5
Meaning
A strange-quark (s) is a type of quark with a charge of \(-\frac{1}{3}\) and a strangeness of -1.
About Strange-quarks
- The strange-quark is denoted with a lower case s.
- The strange-quark decays via the weak interaction into a down-quark, losing it's strangeness.
| Quark | Charge/e | Strangeness | Baryon Number | Lepton Number |
| \(Q=-\frac{1}{3}\) | \(S=-1\) | \(B=+\frac{1}{3}\) | \(L=0\) | |
| \(Q=+\frac{1}{3}\) | \(S=+1\) | \(B=-\frac{1}{3}\) | \(L=0\) |
