Multiquark hadrons. I. Phenomenology of Q 2 Q ¯ 2 mesons
Year: 1977
Type: article
Abstract: The spectra and dominant decay couplings of ${Q}^{2}{\overline{Q}}^{2}$ mesons are presented as calculated in the quark-bag model. Certain known ${0}^{+}$ mesons [$\ensuremath{\epsilon}(700),{S}^{*},\ensuremath{\delta},\ensuremath{\kappa}$] are assigned to the lightest cryptoexotic ${Q}^{2}{\overline{Q}}^{2}$ nonet. The usual quark-model ${0}^{+}$ nonet ($Q\overline{Q} L=1$) must lie higher in mass. All other ${Q}^{2}{\overline{Q}}^{2}$ mesons are predicted to be broad, heavy, and usually inelastic in formation processes. Other ${Q}^{2}{\overline{Q}}^{2}$ states which may be experimentally prominent are discussed.
