Detailed explanation-1: -Baryons, Mesons, Leptons shows the masses of the three elementary particles in decreasing order.
Detailed explanation-2: -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.
Detailed explanation-3: -Current particle physics identifies three basic types of known elementary particles: leptons, quarks and gauge bosons. The known leptons are the electron (e), muon () and tau lepton (), and their corresponding neutrinos (ne, n, n).
Detailed explanation-4: -Hadrons are the heaviest particles. This group is then spilt up into baryons and mesons. Baryons are the heaviest particles of all, followed by mesons. Leptons are the lightest particles.
