Baryons are hadrons created through the strong interactionThey consist of protons and other hadrons that decay into protons (e.g. neutrons)They are made of three quarks (qqq).They decay into protons and pions. Mesons are hadrons that do not include protons in their decay products.They are made of quark anti quark pairs.Baryons quark composition:
Mesons quark composition:
| proton | uud |
| neutron | udd |
| π+ | ud̄ |
| π- | dū |
| π0 | uū or dd̄ |
| K+ | us̄ |
| K- | sū |
| K0 | ds̄ |
