Exotic meson — Non quark model mesons include #exotic mesons, which have quantum numbers not possible for mesons in the quark model; #glueballs or gluonium, which have no valence quarks at all; #tetraquarks, which have two valence quark antiquark pairs; and… … Wikipedia
Quark model — In physics, the quark model is a classification scheme for hadrons in terms of their valence quarks, i.e., the quarks (and antiquarks) which give rise to the quantum numbers of the hadrons. These quantum numbers are labels identifying the hadrons … Wikipedia
Pseudo-Goldstone boson — Pseudo Goldstone bosons arise in a quantum field theory with an approximate symmetry such that if the symmetry were exact, then there would be spontaneous symmetry breaking (SSB) and the consequent formation of Goldstone bosons. The properties of … Wikipedia

subatomic particle — or elementary particle Any of various self contained units of matter or energy. Discovery of the electron in 1897 and of the atomic nucleus in 1911 established that the atom is actually a composite of a cloud of electrons surrounding a tiny but… … Universalium
