| Abstract: | The annihilation and relativistic corrections to the Cornell potential is given and the mass spectra of heavy quarkonia are calculated. A good fit to available experimental data on the mass spectra is obtained and the effects of both the annihilation and the relativistic corrections on the hypersplittings of quarkonium states are discussed. |
| |
| Keywords: | heavy quarkonium mass spectrum relativistic correction annihilation potential |
