discovery of the top quark , if confirmed , has one line of subatomic building balls wherein existence is predicted by the underlying theory , calling the standard model , of the materials and properties that comprise the major origin of motion and energy . in the whimsical encyclopedic of modern physics , the secondary elements are called quark , leptons and bosons .
Quarks, leptons, and bosons are the three elementary particles of physics according to the Standard Model.
