Quarkonium and Power Law Potentials

Abstract

The spectra and decay rates of $c\bar{c}$ and $b\bar{b}$ levels are well described, for the most part, by a power-law potential of the form $V(r)=\lambda (r^{\alpha }-1)/\alpha +const.$, where $\alpha \simeq 0$. The results of an up-to-date fit to the data on spin-averaged levels are presented. Results on electric dipole transitions in systems bound by power law potentials are also presented, with applications to the bottomonium system.
