【 摘 要 】

Theoretical developments and applications of an effective QCD Hamiltonian in theCoulomb gauge are summarized. BCS, TDA and RPA many-body diagonalizations in the quark andgluon sectors are reported for meson and glueball spectra, respectively. The modelglueball Regge trajectories are in good agreement with the established pomeron and arecently observed odd signature daughter. Using the pomeron-glueball connection and vectormeson dominance, glueball photoproduction cross sections and decays are calculated and aglueball experimental signature is predicted. The pseudoscalar-vector meson masssplittings are also investigated using a hyperfine interaction based upon transverse gluonexchange. An improved meson spectrum is obtained and the dominant role of chiral symmetryin the p-r mass difference isconfirmed.
