Relativistic description of quarkonium

Physical Review D, 1987
A relativistic (four-spinor) model Hamiltonian for quarkonium is proposed in the context of the two-particle Dirac equation. Identification of the usual linear potential as an effective mass leads to a very successful global description of quarkonium as characterized by the spectrum of meson states.

Production of scalar-quarkonium int-quarkonium radiative decays

Physical Review D, 1985
We consider the production of the $^{1}\mathrm{S}_{0}$ bound state of scalar top quarks in the radiative decays of $^{3}\mathrm{S}_{1}$ t-quarkonium. We find that branching ratios as large as 0.1% can be obtained for certain supersymmetric-particle masses.

Concavity of the quarkonium potential

Physical Review D, 1986
The heavy-quark--antiquark potential is shown to be a monotone nondecreasing and concave function of the separation. This property holds independent of the gauge group and the details of the matter sector.
