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.

Cosmic Production of Quarkonium?

Physical Review Letters, 1986
It has been suggested that pair annihilation of heavy Majorana fermions in the galactic halo into quarkonium plus a monochromatic photon could occur at an observable rate. Here we show that a calculation of Srednicki, Theisen, and Silk seriously overestimates the rate for this process, by an ordre of magnitude or more, as a result of neglecting the ...

Nonsingular quarkonium potential

Physical Review D, 1987
It is shown that the appearance of singular terms in the quasistatic potential models of quarkonium can be avoided with the use of an improved quasistatic approximation, which yields a nonsingular quark-antiquark potential.

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.

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.
