discovery of the top quark , if proven , completes one set of protons building steps its existence is predicted by the standard system , called the standard model , of the particles and energies that determined the fundamental nature of motion and energy . in the offbeat lexicon of neoclassical physics , the elementary particles are called bosons , leptons and bosons .
Quarks, leptons, and bosons are the three elementary particles of physics according to the Standard Model.
