There are two types of hadrons - baryons and mesons. Baryons are made of three quarks (qqq) and include protons and neutrons.Mesons are made of quark-antiquark pairs and include π mesons and K mesons.Hadrons interact through the strong interaction.Hadrons can interact through all four interactions. If charged they interact through the electromagnetic interaction. Apart from protons which are stable, hadrons decay through the weak interaction.
