Multiquark hadrons. I. Phenomenology ofQ2Q¯2mesons

Jaffe, R. J.·1977·Physical Review D

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.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
