Meaning
A top-quark (t) is a type of quark with a charge of \(+\frac{2}{3}\).
About Top-quarks
- The top-quark is denoted with a lower case t.
| Quark | Charge/e | Strangeness | Baryon Number | Lepton Number |
| \(Q=+\frac{2}{3}\) | \(S=0\) | \(B=+\frac{1}{3}\) | \(L=0\) | |
| \(Q=-\frac{2}{3}\) | \(S=0\) | \(B=-\frac{1}{3}\) | \(L=0\) |
