Particle Zoo

In particle physics, the term particle zoo[1][2] is used colloquially to describe a relatively extensive list of the then known "elementary particles" by comparison to the variety of species in a zoo.

In the history of particle physics, the situation was particularly confusing in the late 1960s. Before the discovery of quarks, hundreds of strongly interacting particles (hadrons) were known and believed to be distinct elementary particles in their own right. It was later discovered that they were not elementary particles, but rather composites of the quarks. The set of particles believed today to be elementary is known as the Standard Model and includes quarks, bosons and leptons.
