Nuclear-bound quarkonium

Physical Review Letters, 1990
We show that the QCD van der Waals interaction due to multiple gluon exchange provides a new kind of attractive nuclear force capable of binding heavy quarkonia to nuclei. The parameters of the potential are estimated by identifying multigluon exchange with the Pomeron contributions to elastic meson-nucleon scattering.

Quarkonium annihilation rates

Physical Review D, 1988
Recent measurements of ratios of quarkonium annihilation rates are used to evaluate the strong fine-structure constant ${\ensuremath{\alpha}}_{s}$. Expressions are presented for QCD radiative corrections with ${\ensuremath{\alpha}}_{s}$ referred to the quark-mass scale.

Relativistic quarkonium dynamics

Physical Review D, 1986
We present, in the framework of relativistic quantum mechanics of two interacting particles, a general model for quarkonium systems satisfying the following four requirements: confinement, spontaneous breakdown of chiral symmetry, soft explicit chiral-symmetry breaking, short-distance interactions of the vector type.

Mixtures of quarkonium and gluonium

Physical Review D, 1985
We study the 2\ensuremath{\gamma} decays of the light pseudoscalar mesons in a model that allows the isoscalar states to have a significant gluonium component, and show that the rates are in good agreement with experiment. The amount of radial mixing in \ensuremath{\eta},\ensuremath{\eta}' states determines these decays completely.
