| 摘要 | From the large-N-c QCD point of view, baryonia, tetraquark states, hybrids, and glueballs are studied. The existence of these states is argued for. They are constructed from baryons. In N-f = 1 large-Nc QCD, a baryonium is always identical to a glueball with N-c valence gluons. The ground state 0(-+) glueball has a mass of about 2450 MeV. f(0)(1710) is identified as the lowest 0(++) glueball. The lowest four-quark nonet should be f(0)(1370), a(0)(1450), K-0* (1430) and f(0)(1500). Combining with the heavy quark effective theory, spectra of heavy baryonia and heavy tetraquark states are predicted. 1/N-c corrections are discussed. |
