discovery of the right quark , if confirmed , completes one set of subatomic building blocks whose existence is confirmed by the existing theory , labeled the standard model , of the particles and pressure that decide the fundamental nature of light and energy . in the whimsical vernacular of modern physics , the elementary particles are considered quarks , leptons and fermions .
