| Question | Answer |
| What are Quarks? | Fundamental Particles of Hadrons |
| Quark combination of a Proton (charge and baryon number of p) | up, up, down (gives charge: +1 and Baryon no: +1) |
| Quark combination of an antiproton | antiup, antiup, antidown |
| Quark combination of a neutron | Up, down , down |
| Quark combination of an antineutron | Antiup, antidown, antidown |
| Quark combination of Baryons in general | For particles: 3 quarks (combo of up and down) For anti-particles: 3 antiquarks (combo of anti up and anti down) |
| Quark composition of Pions and AntiPions | Combo of two of: up, down, anti up, anti down |
| Composition of Pi+ | up, anti down |
| Composition of Pi- (n.b. this is effectively the antiparticle of Pi+) | down, anitup |
| Composition of Pi0 | up, anti up OR down, anti down |
| Composition of K- meson And strangeness | up, anti strange strangeness: +1 |
| Composition of K+ meson and strangeness? | anti up and strange. Strangeness: -1 |
| Composition of K0 meson and strangeness | down, anti strange strangeness: +1 |
| Composition of an anti K0 meson and strangeness | strange, anti down strangeness: -1 |
| What does the weak interaction do? | Changes the type of Quark |
| When is strangeness conserved? | In strong interactions |
| Can you separate Quarks to make solo quarks | NO- even if you supplied lots of energy pair production would just happen, NOT splitting. This is known as QUARK CONFINEMENT. |
