Multiquark hadrons. I. Phenomenology of Q2Q¯2 mesons
Abstract
The spectra and dominant decay couplings of Q2Q¯2 mesons are presented as calculated in the quark-bag model. Certain known 0+ mesons [ɛ(700),S*,δ,κ] are assigned to the lightest cryptoexotic Q2Q¯2 nonet. The usual quark-model 0+ nonet (QQ¯ L=1) must lie higher in mass. All other Q2Q¯2 mesons are predicted to be broad, heavy, and usually inelastic in formation processes. Other Q2Q¯2 states which may be experimentally prominent are discussed.
