Key Stage 5
Meaning
Hadrons are a type of fermion which are subject to the strong nuclear interaction.
About Hadrons
- Hadrons, though extremely small, are not fundamental particles as they are made of quarks.
- Hadrons include:
- Hadrons are affected by the:
| Hadron | Charge/e | Strangeness | Baryon Number | Quark Composition |
|
Proton (\(p\)) |
\(Q=+1\) | \(S=0\) | \(B=+1\) | \(uud\) |
|
Neutron (\(n\)) |
\(Q=0\) | \(S=0\) | \(B=+1\) | \(udd\) |
|
Antiproton (\(\bar{p}\)) |
\(Q=-1\) | \(S=0\) | \(B=-1\) | \(\bar{u}\bar{u}\bar{d}\) |
|
Antineutron (\(\bar{n}\)) |
\(Q=0\) | \(S=0\) | \(B=-1\) | \(\bar{u}\bar{d}\bar{d}\) |
