- Hadrons are made up of quarks, and they are the only particles that are affected by the Strong Nuclear Force. The two types are Baryons and Mesons.
- Baryon examples are protons and neutrons. All baryons except protons are unstable and can decay eventually becoming a proton. They have 3 quarks.
- The Baryon number is a quantum number that must be conserved.
- Beta decay shows this conservation (this decay happens by the weak force, since other particles other than just Baryon's are involved);
n -> p + e- + -Ve
1 -> 1 + 0 + 0
- Mesons interact with Baryons via the Strong force. They are made up of a quark and antiquark.
