MESONS
- A meson consists of a quark and an anti-quark, with binding gluons
- A meson is colour-neutral, as quark and anti-quark have an opposite colour charge. This is why we can observe isolated mesons.
- All mesons are unstable, they decay in less than a millionth of a second.
- Mesons are composite bosons, but not composed of bosons
