From Fermilab’s Don Lincoln: “Physics in a Nutshell – What are hadrons, baryons and mesons?” 

Fermilab is an enduring source of strength for the US contribution to scientific research world wide.

“In this week’s Nutshell, we are going to identify… three classes of particles, hadrons, mesons and baryons and explain how they are related.

First off, all three terms identify classes of particles. Hadrons are particles that experience the strong nuclear force. This means that they contain quarks. A baryon is a type of hadron, and it contains three quarks. A meson is also a type of hadron, and it contains one quark and one antiquark. Making an analogy to the animal kingdom, the term hadron corresponds to the term animal, while the terms meson and baryon might correspond to the classifications mammal and reptile.”

See Don’s full article here. I have given the links to the Wikipedia articles on each of the three sub-atomic particles for those wanting a deeper explication of the subject.

Fermi National Accelerator Laboratory (Fermilab), located just outside Batavia, Illinois, near Chicago, is a US Department of Energy national laboratory specializing in high-energy particle physics.
